Here is CSS example how to show hidden div (on hover):
<div class="showhim">HOVER ME<div class="showme">hai</div></div>
and
.showme{
display: none;
}
.showhim:hover .showme{
display : block;
}
Can I show one div and hide another one at the same time by using only CSS? Here is example how to use JS for this purpose: http://jsfiddle.net/joshvito/GaZQ6/
