1. Vertical alignment, using Transform of CSS3.
If you use CSS, you will be confused: how should I align the elements in the container vertically? Now, with CSS3's Transform, this puzzle can be solved elegantly:
.verticalcenter {position: relative; top: 50%;-webkit-transform: translateY (- 50%);-o-transform: translateY (- 50%); transform: translateY (- 50%);}
Using this technique, everything from single-line text to paragraphs to box is vertically aligned. At present, browsers need to pay attention to the support of Transform. Chrome 4, Opera 10, Safari 3, Firefox 3 and and Internet Explorer 9 all support this attribute.
2. Stretch an element to the height of the window in a specific scene.
You may want to extend an element to the height of the window, and the adjustment of the basic elements can only resize the container, so to extend an element to the height of the window, we need to extend the top-level elements: html and body:html
Body {height: 100%;}
Then apply 100% to the height of any element
Div {height: 100%;}
3. Use different styles based on the file format.
To make it easier to know the goal of a link, sometimes you want some links to look different from others. The following snippet adds an icon in front of the text link to use different icons or pictures for different resources:
