Page Font Size and Tags

Hey, I just transferred over from my .com site to .org in doing so I had to leave behind my beloved Cutline them. I opted for the versatile Constructor Theme, but am having difficulty in the CSS Spreadsheet. I want to increase the size of the font in my page titles above the header and the blog body. I would also like to remove the tags below the posts or at least switch the text to white so they are invisible. Any suggestions would be helpful. Also does anyone know if my facebook and tweet share buttons can be moved to below my posts instead of to the right?

here is my temp link: https://www.nerdygrrl.com.php5-11.dfw1-1.websitetestlink.com/

Thanks!
