Tumblr Themes by James

Step 1:

Click here to go to the customize page. Alternatively you can click on the customize button on your blog.

Step 2:

Click on 'edit html' this will show your current theme code.

Step 3:

Remove all the text in the html box: You can select all text by holding CTRL+A for pc-users and for mac-users you hold CMD+A.

Step 4:

Paste the theme code into the empty edit HTML box. To find a theme code, start at the homepage and select a theme that you like. Then you will be taken to the indervidual page for that theme which features a slide show, links to live previews of that theme and a short description. You will find a button 'Install Theme' click on it and you will be taken to a pastebin page.

Step 5:

On the Pastebin Page the easiest way to copy the whole code is to click on the clipboard (indicated by red arrow). All New and updated themes have a note which states "END OF THEME" to indicate the end of the code.

After you click on the clipboard a message will appear as shown in the screenshot 'TEXT BELOW IS SELECTED. PLEASE PRESS CTRL+C TO COPY TO YOUR CLIPBOARD. (⌘+C ON MAC)'

Step 6:

Paste Code Directly into the empty edit HTML box. Then click the green Update Preview Box.

Step 7:

After completing Step 6 the customize page shoudd show be displaying your new theme. Play around with custom colors, sidebar/header/cover/background images, and other options to tweak the theme to suit your liking. I recommend using a white or light colored background. Make sure your text is clearly visible and remember the KISS Principal (Keep It Simple Stupid).
