It has been replaced by a much more effective way to change the appearance of text: namely, CSS. However, this font tag was deprecated back in 1998 so it doesn't work with the latest version of HTML, HTML5. You would have written the following line of HTML: So say you wanted to change your font to Arial, size 20px, and a nice orange color. You used to be able to simply use the font tag to change the style of text in HTML. So, technically, you’ll be changing font “in HTML.” Inline CSS means your HTML and CSS will be placed together in the body section of your HTML doc. Then add this style attribute to an HTML element, like a paragraph, heading, button, or span tag. Set it to the value you want and place it inside a style attribute. To change font type in HTML, use the CSS font-family property.
