Why Doesn't My CSS Hover Code Underline My Link?

Understanding 'hover' in CSS

When working with CSS, 'hover' is a crucial concept for modifying element styles upon mouse interaction. However, achieving the desired outcome requires correct implementation.

The 'hover' Enigma

Recently, a query arose regarding the inability of the following code to underline a link upon hover:

<a class="hover">click</a>

a .hover:hover {
    text-decoration: underline;
}

Unveiling the Solution

To rectify the issue, we must remember that 'hover' is a pseudo-element. The correct syntax is:

a:hover {
    text-decoration: underline;
}

Alternatively, if a class-name is preferred:

a.hover:hover {
    text-decoration: underline;
}

The 'hover' Class-Name

While using a class-name like 'hover' may seem redundant, it can be applied in situations where you want to toggle multiple properties upon hover by utilizing a separate CSS rule for '.hover'. However, if the sole intent is to underline a link on hover, the a:hover selector remains the preferred choice.
