Difference in IE CSS

1. IE7, IE6 Div + CSS show different width definitions % L7 ^ + e # _ & F/B. C + A1 u

In terms of width definition, the width of IE7 is wider than that of IE6. This is the reason why the webpage may have overflow problems, fortunately, you can change the value or change the percentage. 2. ie7.0 fixed! Important bug. P. Z (F-W) S & Z

Previously due to ie6.0 pair! Important identifies bugs. The box model interpretation in Firefox and IE is inconsistent, resulting in a 2px difference. Most Web Standard designers use this bug to be compatible with ie6.0 and Firefox, that is, using: div {margin: 30px! Important; margin: 28px ;}. However, ie7.0 fixed this bug, so the problem emerged again. How can I be compatible with ie.7.0 and ie6.0 and Firefox?

Many JS pages normally displayed in IE6 cannot be displayed normally in IE7, and no error is prompted. Ie7.0 has stricter requirements on JS syntax, but this specification does not seem to be explained, and it does not clearly tell you how they are "standardized" and "Fan .; P5 I; A * Y3 S3 g

If only Min-width and Min-height are used, the width and height under IE are not set at all. 4 L-R % P &? 6 Q: N2 L For example, to set a background image, the width is important. To solve this problem, you can: 0 w. p'a5 H4 K # {# box {width: 80px; Height: 35px;} HTML> body # box {width: auto; Height: auto; Min-width: 80px; min-Height: 35px ;} 0 K1 B U $ t! J8 A; U6 ^!

But IE does not recognize this, * J'x. z5 J6 I $ D, which uses width as the minimum width. To enable this command to be used on IE, you can place <div> under the <body> label and specify a class for div: ) E % Y, _ & W (x) w9'; O) D.
