add copy button for code block

Hi @gongzhitaao

Thanks for your great work on this.

I wonder if you can add a copy button for code block so that people can copy the code snippets quickly, especially for long and large blocks.

Hey Zilong,

Good suggestion, let me see how easy it will be for a pure css solution.

Hi,

I don't think there is a good solution to copy text to clipboard with one click button for pure css, although I am not an expert on css. Alternatively, maybe we can make the code block copiable when moving mouse to the block using hover feature so that people can Ctrl/Cmd+C to copy. check this https://stackoverflow.com/questions/44418687/making-text-selectable-on-hover-with-css. But this is not good solution for mobile device. I think using js is inevitable if you want to make it work across all devices.
