Using the Wexley template, I'd like to add a banner image and title to my BLOG page (not each individual entry) I'd like it to look similar to this, but with a word BLOG instead of VISION:
https://mbtaarchitects.squarespace.com/vision/
(It's not possible to add other blocks to the blog page, so I have to add some CSS to the header code injection. I've been able to get the word BLOG, however can't figure out how to get an image along with it, and the spacing right...)
