Using a fresh CSS underline works well for large text.

But a good CSS underline works just as well for small pieces of text, especially inline links that connote interactivity and hyperlinking.

About the CSS Underline

The text-decoration property is the CSS property that allows the creation customized underlines. It’s also possible to create a custom CSS underline using the border-bottom property.

Customized underlines have a longstanding history on the Internet. Of course, the standard monochromatic blue underline was originally created to connote hyperlinks to other websites. While this is still the main purpose, underlines have enjoyed a resurgence for decorative purposes as well.

Lastly, it is possible to add even¬†more decorative elements to your underlines, such as dotted underlines, dashed underlines, and the like. While CSSBud doesn’t offer such an ability, we encourage you to explore them on your own!
