I have a button that needs to be centered in it's div class ex. div="sanfrancisco-image". It's placed 17px from the bottom of the box, however it will appear center, even though I've placed justify-self:center; and align-items: center; tabs.
Here's the codepen link: https://codepen.io/holmedw/pen/KrvJEb
.btn {
align-items: center;
position: absolute;
padding: 0 20px;
height: 40px;
font-size: 1em;
font-weight: 700;
text-transform: uppercase;
border: 2px black solid;
border-radius: 1px;
background: transparent;
cursor: pointer;
bottom: 17px;
justify-self: center;
}
