Step 1 - Make Child Theme
go to
Admin CP > Styles & Templates > Style Manager and you will see the themes you have installed listed.
Say the theme name was
Custom, just click the drop down menu for the
Custom theme and choose
Add Child Style. Name it to whatever you want and save.
Step 2 - Configure Header
You will see your child style template listed under the main one. Choose
Common Templates from the child drop down menu box. You will now get the HTML code for the header, footer, etc. In the
header template, edit the HTML to display your new header, whether it be changing the image itself or re-writing the entire header to suit your needs.
Save that.
Step 3 - Applying Style to Subforums
Now go to
Forums & Moderators > Forum Manager
Go which ever forum you want the theme applied and click the edit button.
Go to the
Style Options and choose your child style from the drop down in the
Custom Style for this Forum field. I recommend overriding user choice if you don't want members to choose the theme while browsing (if you want a set theme per forum). Save the changes...Do the same for each forum respectively.
You can make any number of child themes to suit your needs. You can even make totally new custom templates and have different designs for each forum. The possibilities are endless. Also, the templates and themes are not limited to versions. Most themes can be used for many different version of vb3.x.x but there might be minor differences but the steps are the same nonetheless.
