Change Blog Background Image and Change Linked Text Colour

[rockfluff1]

Here's my blog: https://rockfluff.weebly.com/

I've tried some of the suggested ways to do this with the header/footer code but none have worked so far. I'm assuming it's because I'm on a different theme or something. I'd like the blog page to have the same background as all the other pages on the blog. I'd also like text that is hyperlinked to be a different colour (preferably the standard blue) but I'm not sure how to go about that either?

Is it possible to edit CSS to the point where I could have a main central white panel for the content to sit on, with the background remaining the chosen image?

Thanks for any help!

Weebly employees are not able to assist with code edits, but another user may be able to help you out. If you do edit the css/html area of your theme your site would be considered a "custom" theme. It's possible you may not be able to receive assistance from support unless you revert back to a standard Weebly theme. If you are able to add the css override to Settings>SEO>Header your site will still be a standard Weebly theme and it is much easier to troubleshoot. I.e. if you run into an issue, you can remove the code, see if the issues resolves, and the paste it back if the override was not the cause. Just something to think about when you are making these types of edits.
