What is this in CSS?

Things I have tried

I’m currently using minimal CSS theme.

I modified some code to look comfortable, specifically bigger fonts.

After I made font bigger, back and forth arrow (in red square) is not aligned properly.

This is really annoying.

What should I do to make the arrows right?

What I’m trying to do

Try play with this css:

.titlebar-button {
    font-size: 14px;
}

I think that’s the right point but It can’t resolve the problem…
When I input you recommend the arrows go down.
Is there any syntax for titlebar-button alignment?

Try this one (play with “top” value):

.titlebar-button-container {
    top: -2px;
}

It works. I appreciate for your help.
