Page name and nav bar

How do I remove the page name from all pages? (e.g) Contact us page, the contact us doesn't automatically become the title

Also, how do i remove the two lines from the nav bar?

Thanks

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.content-wrap .contact h2 {
display: none;
}
.content-wrapper h2 {
display: none;
}
.header .menu-bar {
border-top: none!important;
border-bottom: none!important;
}
