How to prohibit copying of article content in css
In CSS, you can use the user-select attribute to achieve the effect of prohibiting copying of article content. Just add the "user-select:none;" style to the text element. The user-select attribute is used to set or retrieve whether the user is allowed to select text. When the value of this attribute is set to "none", the text element cannot be selected by the mouse, thereby preventing copying of text.

user-select: auto|none|text|all;
| Value | Description |
|---|---|
| auto | default. Text can be selected if the browser allows it. |
| none | Prevent text selection. |
| text | Text can be selected by the user. |
| all | Click to select text instead of double-clicking. |
