Hide Search Boxes and its webpart

Dear support,
Is it possible to hide the entire horizontal webpart (with grey background) that has the two search engines?

Thanks!

 

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

Code:

.main_search{
display: none;}
 
.header_wrapper {
min-height: 190px;
padding-bottom: 0;
}
.content_wrapper {
padding-top: 20px;
}

 

Can I make it display ONLY on the home page?

 

All pages share same header file, So it is not possible to remove or show search field from any particular page.
