Sticky header hidden by elements when scrolling

bronston59

When using modules in sticky header pages, there is a problem of elements scrolling over header block. Title of Fetaured Stories module, images of slider module, and an icon over module which shows there's a gallery (I think).
All of them are passing over the header block, hiding it.
At present all modules I use are still the ones of full auto installation (quick start). Not yet any changes.
Why does this happen, and how can it be fixed?

Hi bronston59

In the custom css I suggested in other topic, try to change the z-index as below:

.t3-header.affix {
    position: fixed;
    z-index: 100;
    width: 100%;
    top: 0;
}
