To Make text appear italic, use the <i>tag before and after the text</i>that you are adding.
Using the italics tag is very easy, and it can make your website look more professional to the visitor. You can also code your text using CSS. An example if italics in CSS is:
<div class=”your-css”>Some text</div>
Using the italic tag is said by some to help you on the search engines, but other say it makes little difference, but one thing is for sure: It can help with the user experience and that is the most important thing when building your website.
