's height
Yes mom, I did my homework lol
You should then add the CSS rules
.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }
Or you can target it with a child selector
.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }
Background on my own use of this
I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)
HTML
{{flag}}
{{country}}
CSS (option for multiple spans in a div)
.international {
height: 42px;
}
.international > span {
line-height: 42px;
}
In this case if I just had one span I could have added the CSS rule directly to that span.
CSS (option for one specific span)
.intlFlag { line-height: 42px; }
Here is how it displayed for me
