On: I made progress bars using only CSS3. You can use ...

[mappu]

     <div class="progress" style="width: 40%;"></progress>

What? That should be </div> (From the README.md).

Also seconding the simplicity of the project (i guess new years eve is a low-volume time of the year for submissions, but i wouldn't have expected this to be #5 on the front page.. must have hit all the right buzzwords.)
