Breadcrumb links colour should be improve.

Tanushree Gupta → made their first commit to this issue’s fork.

@Tanushree Gupta, I've examined your patch, and I've noticed that the black color (#000) used for the breadcrumb text and link doesn't stand out well against the theme's background color. Therefore, I recommend using white color (#fff) with an underline effect when hovering over a link. Please consider implementing the following code:

.breadcrumb, .breadcrumb a {
    color: #ffffff;
}
.breadcrumb a:hover, .breadcrumb a:focus {
    text-decoration: underline;
} 

I have added the before & after screnshots for reference. Please review

Changes done according to your suggestion.
