CSS Minify Example
Here’s a quick example to show what CSS looks like before and after minification. The design stays the same—only the file becomes smaller and faster to load.
Before (original CSS):
/* Layout helpers
----------------------------------*/
.ui-helper-hidden {
display: none;
}
.ui-helper-hidden-accessible {
border: 0;
clip: rect(0 0 0 0);
height: 1px;
margin: -1px;
overflow: hidden;
padding: 0;
position: absolute;
width: 1px;
}
After (minified CSS):
.ui-helper-hidden{display:none}.ui-helper-hidden-accessible{border:0;clip:rect(0 0 0 0);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}
