Once again we have the common "panel/card/tile" container theme. There's not much new here except for the way I made the buttons take up an entire strip on the bottom:
panel bottom {
flex-shrink: 0;
display: flex;
flex-direction: row;
justify-content: space-evenly;
}
panel bottom button {
display: flex;
margin: 0;
border-radius: unset;
width: 100%;
justify-content: space-evenly;
}
The key to this is setting justify-content: space-evenly on the containing panel bottom, then set the width of each button to 100% with width: 100%. There are other ways to force the buttons to max width, but I've found width:100% is the most reliable method.
