Tumblr is a popular blog platform, which allows users to create their own short-form blog. It’s really simple to just add a photo or a link, without feeling the need to write a bunch of text.
A few years back I made a theme called Strict, that users could download and use for free. Later the guys at Tumblr released their theme directory, then known as the Theme Garden. Strict became pretty popular and has since then been installed over 160,000 times.
As you can see in the image above (1, 2, 3, 4), the theme can be customized a lot, with your own colors, bakground image or fonts. And of course, if you’re comfortable with CSS you can do pretty much anything!
You can install the theme by over here, or read more about it here.
