我这里需要在鼠标移过的时候网站首页之类字样的背景变成暗红 但现在显示的效果却不是那样。然后我要下面的长线断开,而不是连一起。应该怎么做呢?

  • 按照你目前添加的样式,你可这样写:
    .a a{text-decoration:none;background:#fff;display:block;width:自己写px;height:自己写px;}.a a:hover{background:#f00;}
    按照上面的方式,自己调一下 display:block; 是为了让 <a>标签变为实体 ######如果要让 li 的背景变红,我经常在里面加上:onmouseover / onmouseout  或 onmousemove,用js来控制######我还想请教个问题 请问webstorm如何加载字体呢 我要加载微软亚黑的字体
