Small set of XHTML + CSS compatibility Solutions

There are many advantages to using the XHTML + CSS architecture, but there are also some problems. Whether it is because I am not skilled or have unclear ideas, I will first write down some of my problems below, you can find it in other provinces.

1. The box model interpretation in Mozilla Firefox and IE is inconsistent, resulting in a 2px difference. solution:

Div {margin: 30px! Important; margin: 28px ;}

Note that the order of the two margin entries must not be reversed. According to Alibaba Cloud! The important attribute ie cannot be identified, but other browsers can. So in IE, it is actually explained as follows:

Div {maring: 30px; margin: 28px}

If the definition is repeated, execute the last statement. Therefore, you cannot write only margin: xxpx! Important;

2. the box interpretations of ie5 and IE6 are inconsistent. Div {width: 300px; margin: 0 10px 0 10px;} Div width is interpreted as 300px-10px (right filling) -10px (left filled) the final Div width is 280px, while the width on IE6 and other browsers is 300px + 10px (right filled) + 10px (left filled) = 320px. In this case, we can make the following changes:

Div {width: 300px! Important; width/**/: 340px; margin: 0 10px 0 10px}

I don't quite understand what/**/is. I only know that both ie5 and Firefox support it, but IE6 does not. If anyone understands it, please let me know. Thank you! :)

3. UL labels have padding values by default in Mozilla, while in IE, only margin has values. Therefore, we should first define:

Ul {margin: 0; padding: 0 ;}

Most problems can be solved.

4. For the script, the language attribute is not supported in xhtml1.1.CodeChanged:

<SCRIPT type = "text/JavaScript">

You can.

5. If you set the direction of float and text-align in the box container to the same:

{Float: Left; text-align: Left; margin: 0 0 200px ;}

We can make the following changes:

{Float: Left; text-align: Left; margin: 0 0 0 200px; display: inline ;}
