Secrets of CSS Attribute Selector Revealed

CSS Attribute Selector is a very useful and powerful tool that allows us to select and Styling specific elements. These attribute selectors can match and select based on the element's attribute value, where the attribute value appears, and specific characters in the attribute value. This article will reveal the secrets of CSS attribute selectors through specific code examples.

First, let’s learn about some basic CSS attribute selectors. The most common attribute selector is "[attribute]", which is used to select elements with a specified attribute. For example, if we want to select all elements with the "title" attribute, we can use the following code:

[title] {
  color: blue;
}

In this way, all elements with the "title" attribute will have the blue text color applied.

In addition to simple attribute selectors, there are also some more advanced attribute selectors that can be used. For example, we can use an attribute value selector to select elements with a specific attribute value. The attribute value selector is written as "[attribute=value]". The following is an example:

input[type="text"] {
  border: 1px solid black;
}

This code will select all input boxes of type "text" and set their border style to a solid black line.

Another powerful attribute selector is "[attribute^=value]", which can select elements whose attribute value starts with a specific string. For example, if we want to select all elements whose links start with "http://", we can use the following code:

a[href^="http://"] {
  color: red;
}

In this way, all links starting with "http://" will be Apply red text color.

Similarly, there is the "[attribute$=value]" attribute selector, which selects elements whose attribute value ends with a specific string. For example, if we want to select all elements whose links end with ".com", we can use the following code:

a[href$=".com"] {
  text-decoration: underline;
}

This code will underline all links that end with ".com".

Finally, there is the "[attribute*=value]" attribute selector, which selects elements whose attribute value contains a specific string. For example, if we want to select all elements that contain "google" in their links, we can use the following code:

a[href*="google"] {
  font-weight: bold;
}

In this way, the bold style will be applied to all links that contain "google".

By using these attribute selectors, we can easily select and style specific elements without having to write a separate CSS class or ID for each element. This greatly improves the maintainability and flexibility of CSS.

To summarize, CSS attribute selectors are a very useful and powerful tool that can select and style specific elements based on their attribute values. By using attribute selectors we can select elements with a specific attribute or a specific attribute value. In addition, attribute selectors can match based on the occurrence of attribute values ​​as well as specific characters. By taking full advantage of the power of these attribute selectors, we can develop and maintain CSS style sheets more efficiently and flexibly.

The above is the reveal of the secrets of CSS attribute selectors. I hope the code examples in this article can help readers better understand and use these attribute selectors.
