I have been able to adjust the logo in the core.php, and have also added the code I posted above to the function.php which worked. Here are the questions I have at this point:
1. Before uploading images to my site, I scale them to 300×300, there are some exceptions where the original is wider, so I maintain proportions with the height being 300. That said, the images are being made quite a bit larger when they are displayed on the homepage. Images that are 300×300 are appearing quite bigger on the homepage, and within single posts.
Here is an example of a single post where the logo for Noisey is supposed to appear at a size of 300×300:
2. Is there a quick way to change all of the colors associated to each category? I changed them one at a time, and it took me a very long time to do so.
3. As mentioned above, I was able to correctly move the text with the links back to the original source of material I am posting. The links within the sentence are black, is there a way to change the color of just the links in the sentence to the standar blue for a hyperlink?
The text looks like this:
This post was originally published on this site
the words post and this site are the hyperlinks.
Thank you again for all of your help.
