Is it possible to make Search Results transparent?

Solution 1:

I follow this steps to make it possible:

1. Search for gnome-shell.css inside the gnome-shell folder of your favorite theme... or the default one, too.
2. Open the CMD and login as SuperUser.
3. Type nano and drag the gnome-shell.css file to the CMD; hit Enter.
4. Open the search tool using Ctrl+W.
5. Type search-section-separator; hit Enter.
6. Replace the default px value of height for 1px and the background-color value from transparent to rgba(255, 255, 255, 0.16).
7. Go to search-section-content... it's just a few lines down or to the right side of search-section-separator.
8. In background-color, erase the rgba value [Example: rgba(42, 42, 42, 0.775)] and replace it with transparent instead.
9. Change the px default values in border-shadow and border to 0px.
10. Type Ctrl+O and hit Enter to finish the transformation.
