Answer 1

Here's a example to get you started.
The main trick here is the usage of the counters .

• counter-reset
• counter-increment
• counter()

   section { counter-reset: test; } section h3 { counter-increment: test; position: relative; padding-left: 40px; } section h3::before { content: counter(test) "."; position: absolute; top: -4px; left: 0; display: inline-flex; align-items: center; justify-content: center; width: 30px; height: 30px; border-radius: 50%; background: green; color: white; }

   <section> <h3>Section 1 Title 1</h3> <h3>Section 1 Title 2</h3> <h3>Section 1 Title 3</h3> </section> <section> <h3>Section 2 Title 1</h3> </section>
