There are various ways to handle these types of situations. Sometimes to increase the emphasis, I use the <p> tag with in-line styling, as for example:
<p style="font-size: 110%; font-weight: 500"> PUT TEXT HERE </p>
This will give slightly larger (110% instead of 100%) and slightly bolder (500 instead of the normal 400) characters. You can adjust the parameters according to your taste.
