Underline Text Generator

Q: Does underlining play any role in programming?

In programming, the underline character is often used in place of spaces, which are not allowed in variable names in many programming languages. For instance, you can name a variable “variable_one” instead of “variable one”. In addition, some coding conventions use underscores for specific purposes, such as indicating private variables or methods.

Welcome to our underline text generator! Underlined text is a horizontal line drawn under one or more words that you want to emphasize. Although it is mainly used in hyperlinks, it is also a primary way to highlight text in handwriting or typewritten documents, and a secondary means of emphasis in other digital documents. Using a pro underline font generator lets you apply these styles to your digital content instantly.

In this article, we will answer the following questions:

How to underline text properly in software like Google Docs or Adobe Acrobat?
Do you underline book titles or use italics?
How do I use an underline text generator?

🙋 If you need other styles, you can also check out our italic text generator or our subscript generator for scientific notation.

Using underline text for hyperlinks and web design

When using an underline text generator, it is important to understand the context of your content. In web documents and email, underlined text is mainly used to mark hyperlinks. However, URLs and email addresses should not be underlined when they are not clickable, because an underscore in the address will not be visible if the entire address is underlined. To highlight them, it is preferable to use bold text type or insert them between parentheses, square brackets, or single angle brackets.

In handwriting: Are books underlined or italicized?

The practice of underlining originated long before the invention of the printing press, which is why students and writers still frequently ask, “Are books underlined or italicized?” In historical handwriting, underlining served as a means of emphasis equivalent to modern italics or bold text. While you can still use an underline font to make book titles stand out in handwritten notes, modern digital word processors have almost entirely replaced this practice with italics.

🔎 For those working on formal assignments, it is important to follow specific style rules; you can find detailed instructions in our guide on “How to Underline Text” and learn more about books and titles in our dedicated article “Do you Underline Book Titles”.

How to underline text in common software

Depending on the platform, there are several ways to underline a text:

Google Docs: Select the text and click the U button on the toolbar, or use the keyboard shortcut Ctrl+U (Command+U on Mac).
Adobe Acrobat: Use the Underline Text Tool from the toolbar or menu, then click and drag over the text you wish to highlight.
HTML: You can underline text using the < u > tag, although this has been deprecated in HTML5 in favor of CSS.
CSS: Use the text-decoration property with the value underline to customize the color, style, and position of the line.
Markdown: You can use underlining in some Markdown variants. However, this feature is not universally supported (e.g., in GitHub-flavored Markdown, there is no built-in syntax for underlining). But in other markdown processors, you might be able to use HTML < u > tags.
Keyboard: The underline character (underscore) is located on the same key as the hyphen and is typed by holding Shift and pressing the Hyphen key.

Strikethrough and underline are two text styles. Underline places a horizontal line under the text, while strikethrough places a horizontal line through the middle of the text. Strikethrough is often used to indicate that something is incorrect, completed, or deleted.

Why do we underline the valence of electrons in chemistry exercises?

In many schools, students are taught to underline the valence electrons to better visually distinguish these essential particles when doing exercises on chemical bonds. This practice makes it possible to clearly highlight the most important information in handwritten diagrams or notes.
