Plugin development - Adding Foundation 5 CSS changes Craft CMS control panel I am trying to embed a Google Map widget as a field in Craft. I am doing plugin development to achieve it.

Adding a foundation 5 css in a PluginName_FieldType.php file into the getInputHtml() function results in changes is Craft Control panel.

craft()-&gt;templates-&gt;includeCssResource('pluginhandle/foundation.css');

I apologise if it is something silly. I am a newbie to Craft.
I don't use Foundation 5. I've been using Foundation 6, but I'll offer a suggestion based on Foundation 6 usage. 

It looks like your Foundation CSS is overriding the base Craft control panel CSS, specifically the button classes. 

My guess is that because you're including all the Foundation classes available. If you're using the SASS version, you can comment out the parts you aren't using to minimize the size of what you're using from the base Foundation code. For example, you can try to exclude the button classes from Foundation.

Specifically, if you remove the .button styling rules from your foundation.css file, the Craft buttons would go back to normal.
