Overlap text boxes or reduce inner margin of text boxes

Hello dear community

I need some help to find our how I can either overlap text boxes or reduce the margin inside a text box.
There are 3 text boxes lined horizontally and I want to put them more next to each other (right and left sides) ie:
SERVICES WOOD CONTACT    instead of the default text box margins (this are the closer they can be)   
SERVICES       WOOD        CONTACT

Someone could give me a clue?
So much appreciated!

Can you share link to page where you added 3 text? We can help easier
