However, some tools such as firebug, when we review specific elements, listing all CSS selectors Based on the selector's priority helps us to know which selector is valid on the specified element. You can easily see that the selector acts on an element. 1. Attribute Selector Attribute selector allows you to locat

the filter element has a certain attribute, such as the href attribute of a. the attribute selection tends to be determined by the attribute value. For example, a href = "Google.com" and a href = "www.google.cn"If a [href * = Google] is used for determination, both of them match;If a [href $ = cn] is used for determination, www.google.cn is returned.If a [href ^ = WWW] is used for determination, Google.com is returned. Principle: ATT * = VAL: the val

Differences between ATT assembly and intel assembly:1. ATT has a more complex way of writing instant numbers, variables ($), and registers (%. Intel directly uses it.2. the Source and Destination operands of ATT are opposite to those of intel.3. Addressing ATT uses the segment address: (offset, base address, factor) wh

The differences between att and Intel assembly syntax are as follows: 1) att uses $ to represent the immediate number, while Intel's immediate number does not need to be defined. 2) att prefixed the register name with %, but intel did not. 3) att syntax uses the opposite sequence to process source and target operand

For example, any a tag that has an HREF attribute is already available without any action: the condition of link, which satisfies the condition of having a linked attribute, if a tag is accessed, it will have: link:visited two states.

In IE8, the substring matching attribute selector (substring matching attribute selectors) is added in CSS3. The matching rules are similar to those in Regular Expressions: E [att ^ = 'val'] // The substring starts with 'val'E [att $ = 'val'] // The substring ends with 'val'E [
