只是有链接在块和增强它与jquery。对于没有javascript的任何人,它都可以100%优雅地降级。在我看来,用html来做这件事并不是最好的解决方案。
例如:< / p >
<div id="div_link">
<h2><a href="mylink.htm">The Link and Headline</a></h2>
<p>Some more stuff and maybe another <a href="mylink.htm">link</a>.</p>
</div>
div.feature {
position: relative;
}
div.feature a {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
text-decoration: none; /* No underlines on the link */
z-index: 10; /* Places the link above everything else in the div */
background-color: #FFF; /* Fix to make div clickable in IE */
opacity: 0; /* Fix to make div clickable in IE */
filter: alpha(opacity=1); /* Fix to make div clickable in IE */
}
<div class="highlight block-link">
<h2>I am an example header</h2>
<p><a href="pageone" class="block-link__overlay-link">This entire box</a> links somewhere, thanks to faux block links. I am some example text with a <a href="pagetwo">custom link</a> that sits within the block</p>
</div>
这里是CSS
/**
* Block Link
*
* A Faux block-level link. Used for when you need a block-level link with
* clickable areas within it as directly nesting a tags breaks things.
*/
.block-link {
position: relative;
}
.block-link a {
position: relative;
z-index: 1;
}
.block-link .block-link__overlay-link {
position: static;
&:before {
bottom: 0;
content: "";
left: 0;
overflow: hidden;
position: absolute;
right: 0;
top: 0;
white-space: nowrap;
z-index: 0;
}
&:hover,
&:focus {
&:before {
background: rgba(255,255,0, .2);
}
}
}
