我要评论实现效果：
实现代码：
html
<div class="buttons"> <h1>simple hover effects with <code>box-shadow</code></h1> <button class="fill">fill in</button> <button class="pulse">pulse</button> <button class="close">close</button> <button class="raise">raise</button> <button class="up">fill up</button> <button class="slide">slide</button> <button class="offset">offset</button> </div>
css
/*
https://developer.mozilla.org/en/docs/web/css/box-shadow
box-shadow: [inset?] [top] [left] [blur] [size] [color];
tips:
- we're setting all the blurs to 0 since we want a solid fill.
- add the inset keyword so the box-shadow is on the inside of the element
- animating the inset shadow on hover looks like the element is filling in from whatever side you specify ([top] and [left] accept negative values to become [bottom] and [right])
- multiple shadows can be stacked
- if you're animating multiple shadows, be sure to keep the same number of shadows so the animation is smooth. otherwise, you'll get something choppy.
