how can i display a static page without having a menu item for it?

I have 4 pages on my website so far, but i would like only three menu items. The 4th page i would like as a static front page which can be accessed again by pressing the site title. How would I do this? Also when I try to ro-order my menu items so that they change order of appearance on my site they won’t change. also, if possible, how would i be able to increase my site title font past the highest size available as it is not that big really? Also i would like my paragraphs section instead of being a white box to be completely coloured the same as the background of the web site so i can colour the font there white. can i do this?

Would really appreciate the help,
