Problems on content pages when removing grey header at homepage

Hello.
I wanted to remove the grey header on my homepage so that the slider is on top of the page. I pasted this CSS code in the Custom CSS section:

.header_container.not_home {
min-height: 0 !important;
}
@media only screen and (max-width: 480px){
.header_container.not_home {
min-height: 0 !important;
}
.home_container {
margin-top: -270px;
}
}
@media only screen and (max-width: 767px) and (min-width: 480px){
.header_container.not_home {
min-height: 0 !important;
}

It made my home page look great, but now unfortunately my other pages have the page text starting right at the top and the menu bar is covering up part of the text. How can I fix this?
Thanks,
Patrick
