'Boostrap vertical sizing with different style width and height

I am trying to set verticaly icon on profile photo card inside div to be in the middle in white box(div), but dont know why it doesnt works. When I use style="width: 300px; height: 300px; for div square I can center it on horizontaly, but not verticaly :/ Can someone explain me what I am doing wrong?

Anyway is there any way how to resize bootstrap icons except display-1???

Solution 1:[1]

that is because bootstrap sets vertical-align ,

just add .bi::before, [class^="bi-"]::before, [class*=" bi-"]::before{ vertical-align:0 !important; }

.bi::before, [class^="bi-"]::before, [class*=" bi-"]::before{
vertical-align:0 !important;
}
