Can you teach me HTML or how to code Tumblr themes?
No. Tumblr already has a really great tutorial for just that. If you want to learn how to code websites in general, you can visit this website for extensive tutorials as to how to do just that.

How do you get rid of the note on "Space"?
Really. Are you serious. Read the note again. Still can't figure it out? Read it again. Read it until you have memorized every last word. Then follow the instructions provided by the note. Your question is answered on the note itself.

How do you change the font size on your themes?
CTRL+F "font-size" in the code and edit the number. Larger numbers warrant a larger font, and smaller numbers warrant a smaller font.

How do you change the opacity/transparency on your themes?
CTRL+F and edit everything that has to do with "opacity". The larger the number, the less transparent the object.

How do you add a link to the navigation on your themes?
Customize > Pages > Add a Page (or edit a preexisting page) > check off the box that says "Show a link to this page". If you wish to link to an offsite page, just choose "Redirect" under "Page Type".

How do I add unlimited scrolling to "Space"?
You can't. From what unlimited scrolling codes I do know of, they don't work well with horizontal themes.

How can I edit "Space" so that it scrolls vertically?
If you can figure it out yourself, then go ahead and edit it. But there is no short and simple method of editing it. I might edit "Space" myself so that it scrolls vertically and release it to the public when I have time.

Can you make me a custom theme?
Yes, for $5. Click here for more information. I accept money via Paypal. Do note that I cannot make you a theme instantly. I have school, and my education is much more important. I will also make custom websites for personal use or businesses. I consider these a higher priority over Tumblr themes and my charge is significantly higher. Contact me if interested or for further information.
