Hi,
I will try to answer you questions:
- to add a logo, go to
Wp admin=>Jobroller=>settings=>Upload Web Site Logo.
- to add banner image: so to same path :
Wp admin=>Jobroller=>settings=>advertising=> you find there 2 areas , add thecode of the baners ( header and job listing ad)
- Jobroller is not crypted, so you can add the code you where want
in condition you have some based php skills.. about your question, it depends on the area/file, you need to add the social media icons... if you tell where, we can point the file you need to add the code in.
- to adjust the width, it will require some css skills, and few mods to be implemented.. ( explain more your needs)
I hope I could help You.
