text-decoration-line 1t4z49
The text-decoration-line property is used to add decoration to text in form of lines: above the text, below the text, or over the text, or to remove any existing decorations. 2g6l3c
It also accepts a value which causes text to blink, and which, although valid, is now deprecated.
The text-decoration-line property accepts one or more whitespace-separated values.
The line-through value is usually used to “strike out” lines of text that have been deleted or changed. Authors are encouraged in this case to use HTML elements such as <del> and <s> to preserve the semantics of such text, so that the meaning (Deletion) is still preserved even when styles are disabled on the page.
Anchor links have a default underline applied to them, which is good for accessibility, as some people depend on the presence of underlines to detect links on a page. So, even though removing the underlines is possible using text-decoration-line: none, it is highly recommended, for accessibility reasons, to keep the underlines or style them differently to match the overall style of the page, instead of completely removing them, unless another visual indication exists that indicates that a piece of text is in fact a link.
