I'm having a little trouble creating a css effect and don't even know what to Google to find code snippets.
I have been tasked with creating a progress bar. The bar has 3 steps. Each step is represented by a circle and between the 3 circles there should be a horizontal line and the name on the step above the circle. Circles and names are easy but how do I create the vertical line that goes between the 3 circles without disturbing the other content ?
Any help is appreciated. Thanks in advance.

Hello, I'm running into a problem where I want to use rems as a unit, so I set the html font-size to 62.5%, which I've seen as a common practice, which should give me 1rem = 10px (because the default font-size should be 16px). But, when I go to use these newly set rems the styles on the page using them are larger than what they should be. For instance, I set a margin bottom to 8rem expecting 80px but on the page its displayed as 120px, despite me inspecting it with dev tools and it saying its using 8rem. I'm just so confused what could be making these rem larger than 10px / rem. I'm using Chrome if that matters. Any ideas? I know this is common practice.
