In the above HTML document, we have a hyperlink to "https://github.com/". The CSS style `text-decoration: none;` prevents the link from being underlined.
While removing underlines can be an aesthetic choice, keep in mind that underlines provide a clear visual cue that a text is a hyperlink, improving accessibility. Always consider your audience and how your design choices impact usability, particularly for those who might be visually impaired or those who rely on assistive technology.
