18. It is best to set the CSS style of hyperlinks in this order: L-V-H-A. That is, This can be avoided Some hyperlinks that have been visited will no longer have hover and active styles

25. Set the height and line height of the element to the same value to vertically center the text

　27 . If a browser that supports WEB standards sets a fixed height value, it will not be stretched like IE6, but you want to set a fixed height and be able to be stretched? The solution is to remove the height attribute and set min-height for compatibility. IE6 that does not support min-height can be defined like this: { height:auto!important; height:200px; min-height:200px; }

　28. Solution to the problem that IE cannot set the scroll bar color in web standards: The setting of body in CSS is changed to
