Just some funzies with CSS3 animations. If you are worried about super deep browser support, use a GIF.
<div class="loader">
<span></span>
<span></span>
<span></span>
</div>
.loader {
text-align: center;
}
.loader span {
display: inline-block;
vertical-align: middle;
width: 10px;
height: 10px;
margin: 50px auto;
background: black;
border-radius: 50px;
-webkit-animation: loader 0.9s infinite alternate;
-moz-animation: loader 0.9s infinite alternate;
}
.loader span:nth-of-type(2) {
-webkit-animation-delay: 0.3s;
-moz-animation-delay: 0.3s;
}
.loader span:nth-of-type(3) {
-webkit-animation-delay: 0.6s;
-moz-animation-delay: 0.6s;
}
@-webkit-keyframes loader {
0% {
width: 10px;
height: 10px;
opacity: 0.9;
-webkit-transform: translateY(0);
}
100% {
width: 24px;
height: 24px;
opacity: 0.1;
-webkit-transform: translateY(-21px);
}
}
@-moz-keyframes loader {
0% {
width: 10px;
height: 10px;
opacity: 0.9;
-moz-transform: translateY(0);
}
100% {
width: 24px;
height: 24px;
opacity: 0.1;
-moz-transform: translateY(-21px);
}
}
Make the text color transparent but add a shadow:
.blur {
color: transparent;
text-shadow: 0 0 5px rgba(0,0,0,0.5);
}
Blurry
More browsers support color than text-shadow though, so you might want to do feature detection. Or, leave the color property and do enough shadowing that it appears blurry anyway (demo).
body {
font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif;
font-weight: 300;
}
Might as well use the nicest Helvetica you can...
a {
display: block;
background: url(sprite.png) no-repeat;
height: 30px;
width: 250px;
}
a:hover {
background-position: 0 -30px;
}
The set height and width ensure only a portion of the sprite.png graphic is shown. The rollover shifts the position of the background image, revealing a different area of the graphic.
