How to style selection highlighting (`::selection`)?
Use the ::selection pseudo-element of CSS to customize the highlighting style when the web page text is selected to improve the aesthetics and uniformity of the page. 1. Basic settings: define background-color and color through ::selection, such as yellow background with dark gray fonts; specific elements such as p::selection can also be limited. 2. Compatibility processing: Add the -webkit- prefix to be compatible with Safari and mobile browsers, and the Firefox and Edge standards are well supported. 3. Pay attention to readability: Avoid excessive color contrast or too fancy, and should be coordinated with the overall design. For example, choose a soft blue base in dark mode to improve visual comfort. Reasonable use can enhance the texture of the interface, while ignoring details may affect the user experience.
Want to add a little personality to the highlighting effect when selecting web page text? You can do it with the ::selection pseudo-element of CSS. It allows you to customize the background color and text color when users select text, making the page look more uniform or more design-oriented.
Here are a few practical tips to help you avoid getting stuck.
Basic style settings
The most common use of ::selection is to modify the background color and font color of the selected text. You can write this way:
::selection {
background-color: #ffcc00;
color: #333;
}This code will show all selected text in yellow background, dark gray fonts. Applicable to the entire page, if you want to only target a specific element (such as a button or paragraph), you can write it like this:
p::selection {
background-color: lightblue;
} Note: Not all CSS properties can be used in ::selection , currently the main support is color and background-color .
Browser compatibility processing
Although modern browsers basically support ::selection , it is recommended to add -webkit- prefix to be on the safe side, especially Safari and mobile browsers:
::selection {
background-color: #ffcc00;
color: #333;
}
::-webkit-selection {
background-color: #ffcc00;
color: #333;
}Firefox can use standard syntax, and IE has also supported it since Edge. If you need to be compatible with old browsers, you may want to consider downgrades or accept default styles.
Avoid affecting readability and user experience
Although it can be customized freely, don't forget to keep it readable. For example:
- Too bright or too dark background will make the text difficult to see clearly
- Too fancy colors can distract attention
Recommended practices:
- Choose a color that coordinates with the overall theme
- Use slightly dark background color on light background
- Improve contrast appropriately under dark background
For example: In dark mode, the selected text can be replaced with softer blue instead of pure white or bright yellow, which is both beautiful and not dazzling.
Basically that's it. ::selection looks simple, but if details are ignored, it can cause visual interference or compatibility issues. Reasonable use can enhance the overall texture of the interface.
