How to use bootstrap-theme.css with bootstrap 3?
css, html, twitter-bootstrap-3
Solution
Upon downloading Bootstrap 3.x, you'll get bootstrap.css and bootstrap-theme.css (not to mention the minified versions of these files that are also present).
bootstrap.css
`bootstrap.css` is completely styled and ready to use, if such is your desire. It is perhaps a bit plain but it is ready and it is there.
You do not need to use bootstrap-theme.css if you don't want to and things will be just fine.
bootstrap-theme.css
`bootstrap-theme.css` is just what the name of the file is trying to suggest: it is a theme for bootstrap that is creatively considered 'THE bootstrap theme'. The name of the file confuses things just a bit since the base `bootstrap.css` already has styling applied and I, for one, would consider those styles to be the default. But that conclusion is apparently incorrect in light of things said in the Bootstrap documentation's examples section in regard to this `bootstrap-theme.css` file:
"Load the optional Bootstrap theme for a visually enhanced experience."
The above quote is found here http://getbootstrap.com/getting-started/#examples on a thumbnail that links to this example page http://getbootstrap.com/examples/theme/. The idea is that `bootstrap-theme.css` is THE bootstrap theme AND it's optional.
Themes at BootSwatch.com
About the themes at BootSwatch.com: These themes are not implemented like `bootstrap-theme.css`. The BootSwatch themes are modified versions of the original `bootstrap.css`. So, you should definitely NOT use a theme from BootSwatch AND the `bootstrap-theme.css` file at the same time.
Custom Theme
About Your Own Custom Theme: You might choose to modify `bootstrap-theme.css` when creating your own theme. Doing so may make it easier to make styling changes without accidentally breaking any of that built-in Bootstrap goodness.
Problem
After downloading a complete pack of bootstrap 3 from http://getbootstrap.com, I noticed that there is a separate css file for theme. How to make use of it? Please explain? I included `bootstrap-theme.css` in my existing bootstrap project, but there is no difference in output.
