Custom CSS to change blog page
I'm making final changes to my website and I have 2 problems with the blog that I would like to change but I can't figure out the custom CSS.
1) I would like to make the title of the blog post larger ("Using Mnemonics To Learn The Alphabet" in the image below").
2) I would like to remove or change the vertical gray line on the left side of the page because I think that it looks strange with the picture/circle.
Please let me know how I can make these changes! Thanks!
