While we don't officially support any third party plugins or add-ons, we do offer some useful advice to help avoid potential issues in your projects.

### Box-sizing

Some third party software, including Google Maps and Google Custom Search Engine, conflict with Bootstrap due to `* { box-sizing: border-box; }`, a rule which makes it so `padding` does not affect the final computed width of an element. Learn more about [box model and sizing at CSS Tricks](http://css-tricks.com/box-sizing/).

Depending on the context, you may override as-needed (Option 1) or reset the box-sizing for entire regions (Option 2).

/* Option 1A: Override a single element's box model via CSS */
.element {
  -webkit-box-sizing: content-box;

/* Option 1B: Override a single element's box model by using a Bootstrap Less mixin */
.element {
  .box-sizing(content-box);
