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. These widgets expect the box model to be content-box instead. Learn more about box model and sizing at CSS Tricks.

You can deal with this conflict by overriding the box model back to content-box just for the third-party widget's section of the page:

{% highlight scss %} /* Box-sizing reset *

• Override an entire region's box model via CSS
• to avoid conflicts due to the global box model settings of Bootstrap. */ .selector-for-some-widget { -webkit-box-sizing: content-box; -moz-box-sizing: content-box; box-sizing: content-box; } {% endhighlight %}
