-webkit-padding-start: 40px; for Chrome
What it is for IE and Firefox?
回答1:
For Firefox, the property name is -moz-padding-start. For IE, there is no counterpart (so far).
You can achieve the same effect using widely supported CSS features at least in a simple scenario where the page as a whole is either in left-to-right or in right-to-left layout and writing direction. Using <html dir=ltr> or <html dir=rtl>, respectively, you can write your CSS code like this:
[dir=ltr] .foo {
padding-left: 2.5em;
}
[dir=rtl] .foo {
padding-right: 2.5em;
}
This would correspond to .foo { padding-start: 2.5em; }. Of course, this approach means some duplication of code. But it works on almost 100% (including IE 7 and newer in Standad Mode).
回答2:
-moz-padding-start: 40px;
-webkit-padding-start: 40px;
-khtml-padding-start: 40px;
-o-padding-start: 40px;
padding-start: 40px;
padding: 40px;
I do not believe IE has a padding-start equivalent.
