Removing Feature Sections

Can I remove the feature sections, or remove 2 to have one feature section that covers the space of all 3? Rather than have 3 separate features, I was hoping to fill the area with "Welcome" content.

THANK YOU!

 

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

Code:

.feturebox .featurebox_inner .featurebox_desc.second{
display:none;
}
.feturebox .featurebox_inner .featurebox_desc.third{
display:none;
}
.feturebox .featurebox_inner .featurebox_desc.first{
width:600px;
}

Now,

Add your text and heading in First Feature section.

 

I tried pasting this code into my custom CSS and it didn't do anything. Actually when I tried using any of the custom CSS suggestions, nothing works. Is there something wrong with my theme? It worked yesterday. HELP! I am trying to remove the 4th feature where the youtube video is...
