Hi paulus1032,
I have helped you change the header block code with the following code:
<!-- HEADER BLOCK -->
<header class="header-block header-block-2">
<div class="container-xxl">
<div class="header-wrap d-flex align-items-center justify-content-between collapse-static">
<div class="t4-navbar mx-auto collapse-static">
<jdoc:include type="element" name="megamenu" />
</div>
<div class="t4-header-r d-flex align-items-center">
<jdoc:include type="modules" name="header-r" style="raw" />
<jdoc:include type="element" name="megamenu-toggle" />
<jdoc:include type="element" name="offcanvas-toggle" />
</div>
</div>
</div>
</header>
<!-- // HEADER BLOCK -->
And add the following code to the tools > Custom CSS:
@media (max-width: 767px) {
.header-wrap {
padding: 13px 0;
}
.header-wrap .border-bottom {
border-bottom: none;
}
.t4-palette-mainnav .nav > li a, .t4-palette-mainnav .nav > li .nav-link {
color: #222 !important;
}
}
