How to remove space in between Header & Slider

Insert this into your stylesheet:

.home .content-block {
   margin-top: 0;
}

Alternatively, you could perhaps remove the following line from theme.css:

.content-block {
   margin-top: 55px;
}

However, I probably would not do that, because pages without a slider might need this margin-top declaration to create some space between the header and content area.

You made a typo.

.home .content-block {
   margin-top: 0;
}

Should be

.home .content_block {
   margin-top: 0;
}

(underscore instead of dash)

Sorry no, that’s my fault. The correct rule is:

.home .content_block {
   margin-top: 0;
}

I accidentally wrote a hyphen instead of an underscore.

It’s working here. Try refreshing the page in your browser.
