I have a style rule I want to apply to a tag when it has two classes. Is there any way to perform this without JavaScript? In other words:
<li class="left ui-class-selector">
I want to apply my style rule only if the li
has both .left
and .ui-class-selector
classes applied.

You mean two classes? "Chain" the selectors (no spaces between them):
.class1.class2 {
/* style here */
}
This selects all elements with class1
that also have class2
.
In your case:
li.left.ui-class-selector {
}
Official documentation : CSS2 class selectors.
As akamike points out a problem with this method in Internet Explorer 6 you might want to read this: Use double classes in IE6 CSS?
You can use these solutions :
CSS rules applies to all tags that have following two classes :
.left.ui-class-selector {
/*style here*/
}
CSS rules applies to all tags that have <li>
with following two classes :
li.left.ui-class-selector {
/*style here*/
}
jQuery solution :
$("li.left.ui-class-selector").css("color", "red");
Javascript solution :
document.querySelector("li.left.ui-class-selector").style.color = "red";
Chain selectors are not limited just to classes, you can do it for both classes and ids.
Classes
.classA.classB {
/*style here*/
}
Class & Id
.classA#idB {
/*style here*/
}
Id & Id
#idA#idB {
/*style here*/
}
All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".
For your case
li.left.ui-class-selector {
/*style here*/
}
or
.left.ui-class-selector {
/*style here*/
}
