How do you prevent text selection on a webpage?

Q: How do you prevent text selection on a webpage?

CSS provides the `user-select` property to control whether users can select text on a webpage. This can be useful for buttons, menus, or elements where text selection is unnecessary or unwanted. `user-select` – Controls text selection behavior. - `none` prevents text selection. - `auto` allows default selection behavior. - `text` forces text to be selectable. - Vendor prefixes like `-webkit-user-select` may be needed for broader browser support. /* CSS */ .no-select { user-select: none; -webkit-user-select: none; /* Safari */ -moz-user-select: none; /* Firefox */ -ms-user-select: none; /* Internet Explorer/Edge */ } Applying the `.no-select` class to an element ensures that users cannot highlight or copy its text. This works across most modern browsers when vendor prefixes are included. Use `user-select: none` only where necessary; preventing selection can reduce accessibility. Combine with `cursor: default` or `pointer` to indicate interactivity when needed. Test across browsers to ensure consistent behavior. Avoid disabling selection on content that users may want to copy or interact with. For more complex interactions, JavaScript can also be used to prevent selection dynamically.
