Turning linkButton into a modal button

[asasass]

This isn’t able to work in the code?

Flex without the invisible div: https://jsfiddle.net/rxjo7can/1/

It is no longer in the middle now.

.buttonContainerC {
    display: flex;
    flex-wrap: wrap;
   /*justify-content: space-around;*/
    align-content: space-around;
    max-width: 569px;
    gap: 10px;
}
