Why does layout formatting in the editor affect the block width?

Question

css

At some point, an indent appeared between the two buttons, which were supposed to be right next to each other. I poked around for a long time why this happened, and by typing in the markup itself I removed the tabulation between the blocks - the indent disappeared.

This is how it happens

. Why did my formatting from the editor somehow affect the width of the content of the block with buttons? First time I'm meeting this. If, after I removed the tab, press tab again, then the indent will also appear, and it will also appear if you put a space instead of Tab.

Answer 1

It's the Inline-block of the slider arrows.
You can set the parent of the arrows to font-size: 0; if you need a quick fix.
