HTML tag

❮ Prev Next ❯

The tag highlights an important part of a text. It can be used for such important contents, as warnings. This can be one sentence that gives importance to the whole page, or it may be needed if you want to highlight some words that are of greater importance compared to the rest of the content. The content of the tag has higher weight for the search engines and the devices, while reading emphasizes the content only with special intonation.

The tag is a phrase tag indicating that a text section has structural meaning.

The content of the tag is displayed as bold. Unlike the tag, which specifies bold text, the tag is a part of semantic markup. The tag is used to bring attention to the text without specifying that it is more important. In most browsers, the default styling for both the and tags is the same. However, if you want to have bold text just for decoration, you should use the CSS font-weight property.

HTML4 defined the tag as implying a stronger emphasis. Unlike it, HTML5 defines it as representing strong importance of the content.

As compared to the tag which changes the meaning of a sentence like the spoken emphasis, gives parts of a sentence that add importance.

To differentiate the text in bold without taking into account its importance use the tag or the CSS font-weight property.
