After learning about centering a button at the bottom-center inside a div, it became clear that it's similar to centering a button within a panel. I managed to achieve this by adding the following CSS to the button:
position:absolute;
margin-left:50%;
margin-right:50%;
bottom: 5px;
The CSS property of the panel is:
position:relative;
The issue I encountered was that it centered the left side of the button, rather than the entire width of the button itself not being centered.
How can I make sure the center of the button is aligned perfectly so that it truly appears centered?
