How to Vertically Center a Div Within Its Parent Using CSS?

In this query, the user seeks assistance in vertically aligning the "Username" and "Form" divs within the "Login" parent div. They have attempted to use the "vertical-align: middle;" property without success.

SOLUTION

The optimal solution for vertically centering divs in contemporary browsers is Flexbox:

#Login {
    display: flex;
    align-items: center;
}

In cases where Flexbox support is lacking (e.g., IE 9 and below), a fallback option via older methods is required.
