Which attribute is used to specify inline styles in HTML?

The attribute used to specify inline styles in HTML is the "style" attribute. When you use this attribute, you can apply CSS rules directly to an HTML element without needing to create separate CSS classes or external stylesheets. This allows for quick and specific styling for that particular element. For example, if you want to change the color and font size of a paragraph, you might write <p style="color: blue; font-size: 16px;">This is a styled paragraph.</p>. This inline approach is particularly useful for small adjustments or for testing styles temporarily.

Other attributes mentioned, such as "class," are used to apply styles defined in CSS classes, while "color" and "font" are not attributes but rather CSS properties that can be set within the "style" attribute. Using "style" gives a direct way to apply those properties inline.
