Flexbox - "space-between" - Zero width elements cause unwanted spaces - html

Question

I am trying to create a kind of "glossary" with flexbox elements. I have a navigation to scroll to the right letter.
There is my Problem:
I placed anchor-links before the first element of each letter. This causes unwanted spaces even if the elements has got width:0px; visibility:hidden; etc. I guess I've tried nearly everything... Hope you've got a solution.
Notice: In this case it is not an option to set the anchor-link to position:absolute!

Answer 1

This solution is not particularly clean. Ideally, someone with more knowledge will provide a better solution.
Remove justify-content property from .letter-around
Add margin-right: auto to glossary-item to create space between the items.
Target the last item in each grid using nth-of-type selector, and remove the margin.
I have changed the glossary-letter from a to a span, I think it makes more sense semantically. I have also moved some of the css rules from .glossary-item to the span.

Answer 2

The most simple solution is to add
.glossary_letter {
display: none;
}
So it fisically will be but your extra space will disappear.

Answer 3

Ok, try another way, it keeps the anchor link working:
.glossary_letter {
flex: 0 0 100%;
}

Answer 4

Found the solution for my own. It's not the best solution I guess, but it works fine.
I filled the spaces calculated by flexbox itself with a margin-left minus value of the percentage that is left. So in my Case the widht of the elements was 22%. This 4x is 88% of the whole container width. That means that the calculated margin of the elements is about 4% of the container width. So if you reduce the margin of the anchor-element by 4% you get the right position of the boxes.
I know that is not the best solution, but it works. If you've got a better one, please show me. :)

Answer 5

Setting justify-content: space-around is basically the same as setting auto to left and right margins to all flex items (the available space will be distributed equally on the left and on the right of each of them). So, to exclude some items from available space distribution, you can remove justify-content and set the equivalent margins only to the needed items:
