How do I get my links to glow on :hover with CSS3? [duplicate]

Glowing Text (HTML CSS)

So I'm looking for a 100% css solution for a text glow effect. I tried text-shadow but I couldn't get it looking how I wanted. I was able to achieve the effect with box-shadow. However, that only glows around the outside of the elements edges, and leaves the inside blank. Here is a picture:

How do I get a nice looking outer glow like above, without the blank inside?

my code is just a simple <li><a></a></li> , with hover css on both the li, and a tags.

Thanks in advance.

a:hover { text-shadow: 0 0 5px #ff0000; }

回答2:

what about a text-shadow on hover

like this

<li>
  <a></a>
</li>

css

li a:hover {
  text-shadow: 2px 2px 10px #000000;

  filter: dropshadow(color=#000000, offx=2, offy=2);
}

You can do this with an extra element

jsfiddle example (or fullscreen)

HTML

<ul id="nav">
    <li><span></span><a href="#">Home</a></li>
    <li><span></span><a href="#">Products</a></li>
    <li><span></span><a href="#">Really Long Nav Item</a></li>
</ul>

CSS

#nav {background-color:#000;overflow:hidden;}
#nav li {float:left;position:relative;}
#nav a {display:block;background:transparent;color:#fff;font-weight:bold;text-decoration:none;padding:20px;position:relative;}

#nav li:hover span {
    position:absolute;
    left:50%;top:50%;
    margin-left:-35%;
    width:70%;height:0px;
    box-shadow:0 0 20px 12px rgba(150, 180, 200, .6);
    border-radius:10px 6px;
}

Potentially you could skip the extra <span> element and do this with the :before pseudo-element on the anchor or list item
