I would like to start by saying thanks for such a great theme. and Special thanks for giving us the option to add a custom background image that was very important for us.
I am however running into a bit of a bump while trying to properly set up the header for the forums.
a- I am trying to increase the size of the logo top left corner.
b- I am trying to change the header color to match with the logo background as for some reason I am not sure how to get discourse to accept a .png image that will go along any header color. Without discourse changing it to a jpg and adding automatically adding the background.
The image below will show what I have now
I know there were a few mentions above about this and creating a custom component to override the CSS however I am not very familiar with CSS and I am not sure what lines to add where in my custom component I created.
