Problem navbar bootstrap in Wordpress

Question

A customer asked me to increase the size of the navbar, so far so good. I increased and had no problem, however, when I go down the page and rise again, the navbar goes behind the slider.

Answer 1

Problem with z-index. Let your navbar that will work.

.navbar {
    border-bottom: 0px solid #d1d1d1;
    padding-top: 20px;
    z-index: 3;
}
