Do you want to use the underline tag in HTML? In the past, the HTML code for underlining text was the simple tag. However, this method has been abandoned in favor of the much more versatile CSS «text-decoration» style property. Using CSS ensures your code stays future-proof. This wikiHow will show you how to underline text in CSS using the current «text-decoration» method, as well as the past deprecated method of HTML.
- The tag is deprecated, meaning it technically works, but it’s not recommended to use.
- When using CSS, use the «text-decoration» CSS style property to underline text.
- While underlining takes only a few steps, consider other methods for emphasizing text. Underlining may confuse your readers.
Using CSS
- Text-decoration is shorthand for text-decoration-line, text-decoration-color, text-decoration-style, and text-decoration-thickness.
- In older versions of HTML, this element used to be known as the «Underline» element. Using the tag is deprecated, meaning it is still allowed but not recommended to use.
- Using the «text-decoration» property is a newer, better alternative to underlining.
- You can use Windows Notepad to create a simple CSS stylesheet.
Use the tag when you want to underline a certain piece of text. Place the opening tag along with the «text-decoration» property where you want to start underlining. Place the closing where you want it to stop. [2] X Research source
span style="text-decoration: underline;">This will be underlined.span>
Declare HTML elements in the section of your page. You can also do this on the CSS style sheet. You can make the underlining process much easier by declaring HTML elements to style. For example, to make all of your level 3 headers underlined, add the following to your CSS style section:
html> head> style> h3 text-decoration: underline; > style> head> body> h3>This header will be underlinedh3> body> html>
Define a CSS Class Style. You’ll be able to quickly underline at any time. In your style sheet or section, you can create classes to call later. The class can have any name you’d like.
html> head> style> .underline text-decoration: underline; > style> head> body> You can use this class to div class="underline">quickly underlinediv> different parts div class="underline">of your contentdiv> body> html>
Consider other methods for highlighting text. Underlining should be avoided to keep from confusing your reader. One popular method is to use the tag, which italicizes text. You can use CSS to further define this tag for unique emphasis.
html> head> style> em color: red; > style> head> body> Anything that uses the em element will be em>italicized (because of the default settings), as well as redem> because of the additional style settings added above. body> html>
Using HTML (Deprecated)
Avoid using the old tags. This has been «deprecated», which means it works but is no longer in use or recommended. This is because HTML is not designed to style content. The tag will still work, but it is now supposed to represent text that is different than the other text, such as misspelled words.
Use the tags to underline (demonstration only). There is virtually no case where you should be using this method anymore. However, it can be good to know how it was used in the event you have to update an old website.
html> body> The old underline tag in HTML u>allowed you to underline things quicklyu>, but it made things a mess when other style elements got involved. This is why modern underlining is accomplished using the "text-decoration" CSS element. body> html>

There are many potential reasons, check that you have the correct image file path for the image. If the image shows on a computer but not a mobile phone, check if the style sheet has different rules for images on mobile devices.

How to underline a text in HTML?
Underlined text is used to help draw attention to the text.
We use the tag, to underline a text in HTML. It represents a text in a different style from another text in the content of the web page.
We can also use the style attribute, to underline a text in HTML. The style attribute specifies an inline style for an element. This attribute is used inside the HTML
tag, with the CSS property text-decoration property.
Syntax
Following is the syntax to underline a text in HTML.
The content to be underlined

text-decoration
The text-decoration shorthand CSS property sets the appearance of decorative lines on text. It is a shorthand for text-decoration-line , text-decoration-color , text-decoration-style , and the newer text-decoration-thickness property.
Try it
Text decorations are drawn across descendant text elements. This means that if an element specifies a text decoration, then a child element can’t remove the decoration. For example, in the markup
This text has some emphasized words in it.
, the style rule p < text-decoration: underline; >would cause the entire paragraph to be underlined. The style rule em < text-decoration: none; >would not cause any change; the entire paragraph would still be underlined. However, the rule em < text-decoration: overline; >would cause a second decoration to appear on «some emphasized words».
Constituent properties
This property is a shorthand for the following CSS properties:
Syntax
text-decoration: underline; text-decoration: overline red; text-decoration: none; /* Global values */ text-decoration: inherit; text-decoration: initial; text-decoration: revert; text-decoration: revert-layer; text-decoration: unset;
The text-decoration property is specified as one or more space-separated values representing the various longhand text-decoration properties.
Values
Sets the kind of decoration used, such as underline or line-through .
Sets the color of the decoration.
