Page-header bootstrap class is malfunctioning

I just started learning bootstrap and currently I'm working with bootstrap v5.2.0. I attempted to create a header with a line using the class="page-header" but the header line is not showing up. Can someone please clarify why?

Answer №1

The .page-header class was phased out in Bootstrap 4 and has been completely removed in Bootstrap 5.

According to Migrating to v4 - Bootstrap

The .page-header class was removed because all its styles can now be achieved using utilities.

The emphasis now is on utilizing utilities instead. You can now replicate the .page-header styles by using .pb-2 mt-4 mb-2 border-bottom. The beauty of these utilities lies in their flexibility for customization.

Answer №2

The class .page-header was removed from Bootstrap 4. For more information, you can visit https://getbootstrap.com/docs/4.6/migration/#typography. However, you can achieve a similar effect with the following CSS:

.page-header {
    padding-bottom: 9px;
    margin: 40px 0 20px;
    border-bottom: 1px solid #eee;
}
