To change the text font in HTML, use the style attribute. The style attribute specifies an inline style for an element. The attribute is used with the HTML <p> tag, with the CSS property font-family, font-size, font-style, etc.
HTML5 do not support the <font> tag, so the CSS style is used to change font. The <font> tag deprecated in HTML5.
Just keep in mind, the usage of style attribute overrides any style set globally. It will override any style set in the HTML <style> tag or external style sheet.
Example
You can try to run the following code to change the font in HTML
