HTML strong: Main Tips

  • HTML strong tags emphasize important information in an HTML page.
  • In most browsers, it will be shown as bold text. HTML <b> tags work in the same manner.
  • <strong> belongs to the group of semantic tags.
  • HTML strong element supports all global attributes.
  • You must use both starting and ending tags.

How to Bold Text in HTML

When you need to mark some text as more important, you can use HTML strong tags:

Example
<p>This is <strong>important</strong> text.</p>

Most browsers will show it as bolded text. However, some older browsers might underline it instead.

CSS vs. <strong> vs. <b>

If you are looking at how to bold text in HTML, you should know there are actually three options:

If all you need is bold styling, you can modify the CSS font-weight property to bold:

Example
strong { 
    font-weight: bold;
}

Then, there are two types of tags in HTML for bold text. <b> is good when you need to style your text in bold, but without any extra emphasis.

HTML <strong> tags have more of a semantic meaning. They represent text that is more important than the remaining part.

Example
<p>This <b>sentence</b> is <b>bolded</b> randomly - <b>no</b> bolded
<b>word</b> is <b>more</b> important <b>in</b> any <b>manner</b>.</p>

<p>Now in <strong>this</strong> sentence, we put
special <strong>emphasis</strong> where it <strong>matters</strong>.</p>

Note: it's also common to use <strong> for notes and warnings in the page - just like in the beginning of this blockquote.
