Mobile Searchbar Offscreen

Hi guys,

I currently use SearchIQ for my site to let users quickly through our ‘wiki-like’ info. I’ve had no issues for months up until now. I recently started to optimize the site for mobile viewing as well, and all the search bars on-site (minus the widget in the blog post sidebar) appear halfway offscreen like so: https://gyazo.com/7cf883b9d86bcbac42b10eb3a2d9c986

I’ve tried a bunch of different fixes but nothing seems to work (I’m a beginner when it comes to code, so that probably has a lot to do with it). I really need to be able to make the bar responsive to mobile view, any help would be appreciated.
