In HTML, this tag indicates that text should be strong. In most browsers, this logical style maps the the physical style of bold. To use it, put <strong> before the start of text you want to be "strong" and put </strong> at the end of what you want to be "strong".
For example, typing
Hi, <strong>dude</strong>
will render as
Hi, dude.
Note that this tag is not case-sensitive, so you can use strong or STRONG.
This tag replaces the deprecated <b> tag.
