To make your website display text that is in BOLD, use the <strong>tag before and after</strong> the text you are adding.
— OR —
You can bold text using CSS:
<div class=”my-text”>This is some text</div>
Adding bold text can make your text stand out more, and it also makes your website look more professional for the visitor. Some say that adding certain text (keywords) can help you out with search, but others say it makes little if no difference. The best part of using bold text properly is that you also increase the user experience on the website.
