I've done everything myself concerning what I need to do for my site, but I can't seem to figure this out. It seems pretty simple, but I just can't get it. I have two themes. One theme is for the main page. One theme is for the blog. I want to match the header, colors, footer, etc. from one theme to the other, so they both match up. I really don't have a budget for this, hence why I've been doing everything myself, but if someone can do it for a very small rate or in exchange for advertising their website on mine, let me know!
Can We see the the two different themes that you are talking about to get a better feel for what you are trying to do ? My first reaction would be to just create a duplicate header in the size that you need and put it on the 2nd blog, then open the CSS file on the 1st blog, get the color codes for the various elements of the theme and change blog #2 to the same colors. Just off the top of my head
Show us the themes you would like to combine .. we may help out. however, combing two themes into one is quite hard then designing a new theme.
