wordpress plugin edit

Hi CODING DONE - just needs to be relocated So unfortunately I hired someone on here who did not do the work as asked - its done but not the proper way. They changed the main template files vs editing the plugin css like I asked. The brief is as follows: Hi I have a wordpress site and it has an instagram feed (plugin based) on it - the plugin developer said the css can be changed to add additional skins to it Basically I need the following 2 new layout shortcodes to be created newgallery1 + should look like the attachment with same name newgallery2 + shold look like the attachment with same name essentially the coding is now there but its in the main theme editor css and needs to be removed from there and put into the instagram plugin css and have a short code that I can easily put into visual composer so for instance all the css would come down to a short cold like [mgl_instagram_user skin="newgallery1"] + [mgl_instagram_user skin="newgallery2"] I need to be able to place this anywhere within the website when need be and change the page thats why it has to remain in the plugin. I also need the main style css or where ever the coding was put to be taken out from the main template Relatively easy changes as the programming is pretty much done just needs to be created w two more shortcodes and added.
