Smile ^_^ Warmup Project

Before we jump into the main team projects, let's get some practice with web development by building a Smile app. It's split into three parts, each with different due dates - (1) HTML/CSS, (2) Javascript, and (3) Testing/Backend.

This is an individual project. You can collaborate and help each other out with parts you're stuck on, but do not cheat and share code. If you use online resources, please reference them with comments in your code. We want you to learn how to do each of these parts. You'll need to know it for the main team project and quizzes.

Smile is an app to share experiences from your day that made you smile and things people did that you are grateful for. It's inspired by the Gratitude Journal. Psychologists did a series of research experiments where they had individuals write down three things they are grateful for each day, and it significantly boosted their happiness. But instead of keeping a super secret personal journal, why not spread the happiness? We know some people write pretty personal things, so all posts will be anonymous.

Check out the happiness research at the end. And if you're really into psychology and happiness, you should take the popular PSYCH 162 Human Happiness course offered right here at UC Berkeley, taught by Professor Dacher Keltner (he's amazing!).

So what can you do in the app? You'll be building out these features:

• Create posts called 'smiles'
• View all smiles posted by everyone
• Like a smile

This is how it is going to look at the end of Part 1 of the project:

Acknowledgments

The Smile project was initially designed by Carina Boo. So, if it does give you a smile, you should thank Carina.

Part 1: HTML/CSS

In part 1, you'll be building the UI (user interface) for the app. It won't be hooked in to a database yet to store the smiles you create - that will come in part 2. This part is just about learning how to build UI using semantic HTML, customize the layout, style it, and make it responsive - responsive, meaning the UI scales nicely for desktop browsers and mobile phone browsers.

Some of you may know HTML/CSS pretty well already. But from last semester's students, over 60% of the students had little experience with HTML and CSS, and we want all of you to be ready when it comes time for team projects. If you're experienced in HTML/CSS and finish early, be nice and help out your classmates by answering questions on Piazza. :)

This Part 1 is structured in several Tasks. This sequence of tasks is for your convenience, so that you can proceed in relatively small steps and check your work. You will submit, and we will only grade, only the end result, after Task 4.

Task 1: Get Started with the Provided Files

---

To help you start we have provided some boilerplate files that you will have to modify to implement the project.

1. Using your GitHub account, find the Smile course repository (https://github.com/necula01/smile_cs169) and create a Fork in your account. You should be able to see it at https://github.com/your_account/smile_cs169.

2. Clone your forked repository on the working machine

git clone https://github.com/your_username/smile_cs169.git

1. You now have a local copy of your smile_cs169 repository. You

2. Create a local branch named part1

git checkout -b part1

1. You will now be editing locally, and remember to commit frequently.

2. You will find the following provided files:

   • static/images
     • favicon.png icon that shows on the browser tab
     • happiness-level.png sprite for three levels of happiness
     • heart.png icon for like button
     • logo.png app logo
   • static/styles
     • main.css where all the styling goes
   • static/html
     • create.html create page
     • index.html home page
   • static/scripts (not needed for Part 1; will need for Part 2)

   You will have to make changes to the .css and the .html files.

3. Open the index.html file with a browser to see the initial version of the provided files.

   • for Chrome, File/Open File, choose smile_cs169/index.html

   At this point if you open index.html it should look like this:

Task 2: The Home Page

---

The first page you'll build is the home page. This page will show all smiles posted by everyone.

Task 2.1: Basic HTML Elements

The home page will go in index.html. Add elements to the page by following the instructions below.

If you are new to HTML or would like a quick review, visit this tutorial.

Add elements for all of the following. Don't worry about positioning or styling them yet. Try to use semantic elements that says something about the content it holds, rather than using the generic <div> for everything. E.g. use a <header> for page and section headers, or a <nav> if we had a navigation bar. Learn more about HTML semantic elements.

1. Header with a logo. Add the logo image in the existing <header> element, using the HTML class "logo". You can find the logo in images/logo.png. Feel free to design your own.

2. "Share a smile" link that points to create.html for posting a new smile. Add the link to the existing <div> with HTML class "create" in the <header>.

3. Smile post. Each post should show its:

4. Title. Use a <div> element with HTML class "title".

5. Happiness level. We'll be using a CSS background-image in Task 2.3 for this one, so for now, just create a <div> with the HTML class "happiness-level" and write "Lvl" in it. Next, we'll customize the post to have a specific happiness levels: add an additional HTML class "happiness-level-1" to the <div> for first post.

6. Story text. Use a story text that is more than a few lines long, so you can fully test the automatic resizing that we'll get to later. Use a <div> element with HTML class "story".

7. Like button for if this post made you smile. Use a <button> element with the HTML class "like" and the text "Like" (we'll change this later to an image).

8. Number of people who this post made smile. Use a <div> element with the HTML class "count", and contents a number.

9. Timestamp for when this was posted. Use a <div> with HTML class "timestamp", and contents of the form "Posted at 1:03pm May 22, 2015".

10. Create 2 more smile posts, with stories about something that happened that made you smile, or something someone did for you that you're grateful for. The posts should have the same HTML structure as the first post. We'll use all 3 posts while customizing layout.

    1. Change the "happiness-level-1" HTML class for the second and third post to "happiness-level-2" and "happiness-level-3", respectively. This will allow you to test the display of the three different happiness levels.

At this point if you open index.html it should look like this:

Task 2.2: Getting the Layout Right

Now let's customize the layout and positioning of the elements. You'll be writing CSS in /styles/main.css. You will also have to make small changes to index.html.

If you are new to writing CSS or need a quick review, see this tutorial.

An important web design philosophy is the separation of content (HTML) from the presentation of content (CSS). So, even though you are able to write inline CSS in HTML tags, please don't do that!

1. The whole header should be as wide as the browser window. (Hint: display: block, percentage width)*
2. The logo should be centered horizontally within the header. (Hint: text-align)
3. The <div> that contains the Share a smile link should be as wide as the browser window. Use the HTML class "my-button" for the link element. The link itself should also be as wide as the browser window. (Hint: display: block, percentage width). You can test that this works properly, if you see the mouse cursor changing for the entire width of the window.
4. The title of each post should be centered. (Hint: make the <div> as wide as the browser window, and the text inside centered.)
5. Position the post content into three columns, so the happiness level is on the left, the story text is in the center, and the like button along with the like count is on the right. The width of the happiness level column and like button column should be constant (e.g., 80px), while the story text column should scale wider if you widen your browser window. (Hint: wrap the happiness into a separate <div> with HTML class "happiness-level-col", wrap the story into a separate <div> with HTML class "story-col", and wrap both the like button and the count into a <div> with HTML class "like-col". Set a fixed width for the level column and the like column, and set width: calc(...) for the story. Use float: left on all three cols, and use clear: left on the <div> that follows the floating elements)
6. The happiness level should be centered horizontally in the column.
7. The number of people who liked the post should be right underneath the button and centered.
8. The timestamp should be underneath the story text. (Hint: use margin-left to add enough margin to it to make it align with the story text.
9. The header (including the logo and Share a smile button) should be always stick to the top and remain visible on the screen as you scroll. (Hint: position: fixed; set margin-top for the mainbody to ensure it is not hidden by the header; also set background-color on the <header> to ensure that the posts scroll underneath.)

* We provide hints to help guide those with less CSS experience. If you know a different/better way to implement the same styling, feel free to use your way.

At this point if you open index.html it should look like this. If you scrolled it down a bit the header should stays fixed:

Task 2.3: Stylin' It Pretty

It's coming along! Now let's style it nicer and make it look like an actual app. We only have the following styling guidelines as far as what we're grading you on. You can any additional styling to make it look however you think looks awesome. For this task you only need to edit /styles/main.css.

1. Pick a nicer font-family than the default Times New Roman for your app. Check out browser-supported fonts or choose from hundreds of free Google Fonts.

2. The font-size for posts title should be larger than the story text. (Hint: use percentages)

3. Add nice background-color to the <header>, the <body> and the posts, so that the header stands out from the list of posts, and the margin between posts is visible.

4. Add padding to your containers. You can decide how much and on which elements.

5. Add more margin to each smile post so there is more spacing in between posts.

6. We want the Share a smile link to look like a button. Add style definitions for the "my-button" class (which we used on the link element) to have: background-color and border, remove the default link underline on the link element. (Hint: text-decoration). To make it look more like a button you may want to use slightly wider borders and slightly darker colors, on the bottom and right side.

7. On hover of the Share a smile button, the background-color should change. (Hint: check out the :hover selector)

8. Change the like button to use images/heart.png. (Hint: use border: none and background: none to get rid of default button styling and background-image: url('../images/heart.png');; adjust height and width; you can use color: transparent to make sure that the "Like" text you wrote in the HTML does not show up.)

9. Replace the Lvl text with the happiness level icons in images/happiness-level.png. Or create your own three-icon sprite. (Hint: background-image)

   • You'll notice there are 3 images in one png. This is called a sprite. Developers often combine a bunch of icons onto one file to speed up page load time since every image requires a network request. (E.g. this is the sprite Google Doc uses)
   • You'll want to use background-image to specify the image file. Set width to 40px and height to 80px (the size of one icon in the sprite). Set background-repeat to turn off repeating the image.
   • Add CSS definitions for each of the 3 happiness levels (e.g., ".happiness-level-1") to position the sprite so it shows the right icon. Use background-position: ...px ...px.

At this point if you open index.html it should look like this:

Task 3: Responsive Layout for Desktop and Mobile

---

Next, we'll learn a little about how responsive layouts work. There are CSS frameworks like Bootstrap and Foundation which have grid layouts for developers to use just by adding pre-defined CSS column classes. But in this project, we'll learn how to do responsive layouts manually and see how it works under the hood.

At the bottom of styles/main.css, you'll see a @media screen definition. (min-width: 800px) means the styles within this definition applies for browser screens 800px or wider.

1. Change the layout to show smiles in 1 column for screens narrower than 800px, in 2 columns for screens between 800px and 1200px, and in 3 columns for screens larger than 1200px. You can make use of the column-count property. You can test the responsive styling by dragging your desktop browser window larger or smaller than 800px and 1200px.
2. You may notice that when you resize the screen some of the longer smiles are split over multiple columns. To prevent this you may want to add

.smile {
   display:inline-block;
}

At this point if you open index.html it should look like this:

Task 4: The Create Page

---

Next - the create page so we can actually create new smiles! Now we'll be working with forms.

Task 4.1: HTML Form Elements

Open up create.html.

1. Add the logo like you did in the home page.
2. Add a message (e.g., "Tell us something that made you smile"). Add a <div> with HTML class "message" above the form.
3. Inside the form, add a textarea with the placeholder text "Share a smile...", with HTML class "story-input" and name attribute "story".
4. Add a select dropdown with 3 options "Happy", "Really happy", "So ecstatic, I can't stop smiling!" for how happy the moment made you feel. The options should have "value" attribute equal to 1, 2, and 3 respectively. The 3 options will correspond to the happiness level sprite icons. (You can rename the options if you'd like.) Use the HTML class "happiness-level-input" and name attribute "happiness-level" for the <select>.
5. Add a label for the happiness level dropdown and title it "How happy did this make you?". Add it before the select.
6. Add a submit button using <input type="submit"/> with HTML class submit-input.

• In forms, we typically use <input type="submit"> rather than <button>. <button>s are typically used for clickable items that don't take user to a different web page.

1. Change the submit button's text to Post.

• Click on the button. It should take you to your home page. Browsers by default handle clicking on <input type="submit"> to redirect users to wherever the <form>'s action attribute specified.
• After you click, verify in the browser URL box that you have a query string, such as, "?title=title&story=blah&happiness-level=2". This is what happens by default for a form with the method=get, as we have defined our form for now.

1. Last, add a "Cancel" link onto the create form in case the user doesn't want to make the post. On click, take the user back to the home page.

At this point if you open create.html (or if you click the Share a smile button on index.html) it should look like this:

Task 4.2: Getting the Form Layout Right

All the form elements stack up squished horizontally. Let's make it look nicer.

1. We want the form to take 80% of the width of the screen. (Hint: make the form have display: block, the proper width, and margin: auto.
2. Change the title input's width to the full width of the form. (Hint: display: block)
3. Change the textarea to be below the title, with a width equal the full width of the form. (Hint: display: block) Add some margin above and below the textarea. Increase the height of the textarea.
4. Position the happiness level label and dropdown so it's not horizontally next to each other. (Hint: display: block)
5. Position the Cancel and Post button, so the Cancel is on the left, and the Post is on the right. (Hint: display: block along with float: left | float: right)
6. Add some padding and margin to space out elements, wherever you think needs more spacing.

At this point if you open create.html (or if you click the Share a smile button on index.html) it should look like this:

Task 4.3: Stylin' Forms

Last bit for the create form. We'll reuse some of the styling we already did for the home page.

1. Use the same button styling (background, border, hover) as your "Share a smile" button. Except the width should not be 100%. We will reuse the style definition for the "my-button" class. Add the "my-button" HTML class to the Cancel and Post links.

You can style the rest of the form however you'd like - e.g. make the cancel link look like a button, change the font sizes, change the dropdown styling.

At this point if you open create.html (or if you click the Share a smile button on index.html) it should look like this:

You're done! Feel free to add additional styling to make your app look even better. Get creative!

How to Submit

---

We'll use Github Pages to host your Smile app. To set this up:

1. Commit your changes locally. Make sure you are in branch part1.

2. Push the part1 branch to GitHub:

git push origin part1

• You can submit multiple times, after intermediate tasks, but on the deadline you need to have submitted the end result.

1. GitHub has a feature whereby it can host your HTML files. To enable this feature you must have a branch named gh-pages. For now, we will set this to be your submission to Part 1 of the project:

git push -f origin part1:gh-pages

- Now your finished project should be up on http://your_username.github.io/smile_cs169/static
- We will use this url to see and grade your project. Please do not change
  your gh-pages branch until you hear that we have graded Part 1.

1. Watch Piazza and the class web site for the link to a form where you will have to submit the url to your project.
