modify & restyle css on a wordpress plugin

We have a custom jobs "wordpress plugin" on our [login to view URL] website that we use, and we need a CSS specialist that can "re-style" the plugin (via a .css stylesheet) to match our new [login to view URL] website. The wordpress plugin currently has css animations that fit the current website ([login to view URL]) that move the content over to the left when you click on a specific job that a person wants to apply for. The problem is that the same CSS properties are displaying on our new website [login to view URL] (the issue its the content is flying off of the web page) we need the content to remain on the page and also be mobile optimized for viewing on tablets and mobile phones. Our plugin allows us to drop the job module on any page via a wordpress [short code] - We need a skilled developer that wont break our plugin and will style the .css file to work with our modern website. We make use of the Visual Composer plugin so, we don't need to have animations in the css if it doesn't need to be there... If you feel you have the chops to achieve this or have more questions, then let me know! Thanks a bunch! - Ben
