requested the guidance from Julia

• [ ] 1. Change the font to SF Pro Display.
• [ ] 2. Put the Qase logo in the top left corner, where QA is written.
• [x] 3. Correct the order of the links in the menu and the list on the main page, currently Books and Definitions are different in the menu and list.
• [x] 4. If we want to apply new styles, then change the color of the links to #4F46DC, the main text color to #2F2D3C, the secondary text color to #6D6C77.
• [ ] 5. On the Books page, we need to embed links in the text and color them in the link color, and make them not so big if they don't have a text description (if there is, then the size is ok, but the links should still be embedded in the text and made clickable).
• [x] 6. I didn't quite understand why on the Definitions page part of the text is formatted as quotes, but there we definitely need to remove the italics.
• [x] 7. Also, the footer could be made not so tall.
• [ ] 8. Also, the main page lacks some kind of title, probably.
• [x] 9. You can remove the bullet formatting on the main page, just make them lines, but increase the interval between them so there is no right shift.
• [x] 10. Maybe try making the header dark (#2F2D3C).
