How to design? Actually I am a Noob!

Now for any adjustments.
1. If you’d like to only have top and bottom border lines like this…

…then change the line in red to this:
border-bottom: 1px solid #BDBDBD;
border-top: 1px solid #BDBDBD;
2. If you’d like to change the colour of the border line change the section in blue.
3. If you’d like to change the colour of the font adjust the section in pink.
4. If you’d like to remove the search icon (which is really just for show) like this…

…then remove the line in purple.
5. If you’d like the font to be in caps add this line underneath “font-family: verdana;”
text-transform: uppercase;
6. If you’d like to change the width of the search bar adjust the percentage in green.
