How can I build this badge with CSS?-CodePudding

I would like to add a badge to my navbar. It should look like the one in the image below.

My current Approach

I use two divs for this. One above and one below. The lower one should do the rounding.
My approach works not so good and I find it more hacky as good.

Question I wonder if there is a better, cleaner way? Can somebody help me?

Thanks in advance, Max

Really no reason for multiple elements. Note that I've put box-sizing: border-box on your stylesheet. This makes sizing calculations much easier by including padding, etc. Most layout libraries do this.
