Bootstrap for Weebly
Download everything you need: Weebly friendly HTML and BootstrapCDN's CSS and JS here (ZIP) and use it in your own custom Weebly theme.
As with all code and projects licensed under the MIT License: download, study, change, and improve at will.
If you have implementation questions check Weebly's Help Center, Weebly for Developers, and Bootstrap's framework examples first. If you're still stuck feel free to contact me via caitlyncraft.com.
