CSS is not selectable: is this a good thing or a bad thing?

CSS is a language for designing web pages that allows us to control the layout, style and interaction of the page. "Unselectable" (user-select:none) is an attribute provided by CSS, which can be used to prevent users from selecting text content on the page. In many cases, this property is very useful, but in some cases it can be a source of trouble.

Let’s first look at the advantages of the “unselectable” attribute. In some web applications, we may need to display sensitive information on the page, such as passwords or account information, etc. This information is not expected to be copied or viewed by users. In this case, we can use the "unselectable" attribute to prevent users from selecting and copying this information and protect the security of this information. In addition, the "unselectable" attribute can be used to prevent plagiarism, protect the website's intellectual property, and give copyright owners greater control over how their website's content is used.

However, the use of the "unselectable" attribute also has some disadvantages, and it sometimes ruins the user experience. On a website where users often interact, such as an online magazine or news website, users may need to extract or store fragments of articles of interest. At this time, the "unselectable" attribute will be like a high wall, preventing users from extracting their own information. Needed content, this will obviously make the user experience very bad. In addition, in more extreme cases, the "unselectable" attribute may even prevent users from performing some necessary operations, such as copying a reference in a public document, hindering normal academic research and communication.

So, we must use the CSS "unselectable" attribute with caution. We should use this attribute when we need to protect information security and copyright, but when we need to ensure user experience and website interaction, we should try to avoid its use. If we really need to use the "unselectable" attribute, we can use it on certain elements instead of disabling selection of the entire text content. In this case, you can also provide some alternative ways for users to obtain the required information, such as providing download links or copy buttons.

To sum up, we should use the CSS "unselectable" attribute with caution. When we need to ensure the security and copyright of page content, we can use this attribute to help protect the security and copyright of website content; but when we need to ensure user experience and website interaction, we should try to avoid using this attribute, or use something more Flexible ways for users to get the information they need.
