I am trying to align an item to the centre of the page in html using bootstrap flex boxes. For some reason the align-items-centre attribute is not working.

CodePudding user response:
you need to specify the height of your container, vertical alignment will not work without a height
.container {
height: 100vh;
}

What are you trying to achieve? just one element in whole page? Here you go :D
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
