HTML Bold <b> Element
By Christopher Kielty, updated Jan 14, 2019
Use <b> to make text stand out without assigning emphasis. This is usually often rendered as bold text, however, this isn't necessarily what this element is for. Style with CSS.
I kind of think of it as <strong> -- which means of strong importance -- without the strongly important semantic meaning.
This is similar to <i> and <em>, where <i> has no semantic meaning and <em> means emphasis, but both can be used for italicizing text.
The CSS that I use for <strong> and <b> on this page is pretty simple: strong,b{font-weight:bolder}
