CSS中visibility:hidden、display:none、opacity:0、rgba设置元素隐藏的区别
<h3>共同点：</h3><p>visibility:hidden、display:none、opacity:0三者都可以使元素隐藏</p>
<h3>区别在于：</h3>
<p>1、visibility:hidden 保留dom节点，元素在文档流中占据空间，不引起重排和回流；父元素设置该属性时，子元素同样会生效，但可以通过visibility:visible;修改子元素的显示效果；</p>
<p>2、display:none 不保留dom节点，元素直接从文档流中删除，引起重排和回流，子元素同样被删除；</p>
<p>3、opacity:0 设置元素透明度为0，保留dom节点，元素在文档流中占据空间，子元素会继承父元素的opacity特性，但是子元素设置opacity:1;同样不会显示出来。</p>
<p>4、通过给元素设置rgba(x,x,x,0)为透明隐藏效果，但仍然会占据一片空间，且子元素不会受到影响</p>
