Padding-right on body can't be switched off

Current behavior

If I open viewer.js in modal padding-right is always added to the body.

It is done here: https://github.com/fengyuanchen/viewerjs/blob/master/src/js/others.js#L26

Expected behavior

I expect additional option to turn off/on this feature.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Currently is breaks layout in our project.

Environment

Viewer.js version: 1.2.0


Browser:
- [x] Chrome (desktop) version XX

- [ ] Chrome (iOS) version XX
- [x] Firefox version XX
- [x] Safari (desktop) version XX

same here, not even sure, why you need this additional padding...

[mathias22osterhagen22]

same here, it makes all my app litteraly jumping on the left (especially with vuejs app)

[mathias22osterhagen22]

I literally fixed it like this:

let viewer = new Viewer(document.querySelector("#image"), { navbar: false, } });
//here
viewer.close = function(){}
viewer.open = function(){}

Please put this ugly padding in a class that can be overridden.

any news?

I also noticed the same problem with the body being added with a padding-right causing the style on the background to jitter when the viewer pops up.
In addition, if the user has modified the padding-right style of the body after loading the viewer, the value will be lost after popping up the viewer and closing it.
I suggest leaving this part up to the user to define, for example, setting the .viewer-open style.

我也注意到了同样问题，body被添加了一个padding-right导致弹出viewer时背景上的样式发生抖动。
另外，如果用户在加载viewer后又修改过body的padding-right样式，弹出viewer并关闭后设置值会丢失。
我建议这部分逻辑让用户自己定义就好，比如设置.viewer-open样式。
