How to make all cards in mui the same height?

Question

How to make this card have the same height in mui? I don't like setting a fixed height. This will need to change dynamically. All card heights need to be set to the highest height in the website. Between the button and the content we can add space. How do i do this?

The problem you seem to be facing is that you want to use the Material-UI library to create cards with variable content height, but you want all cards to have the same height without setting a fixed height. You also want to add space between the button and the content.

function ItemRow({ page_block }) {
    return page_block.map((page_block_item, index) => (
        <Grid
            justifyContent="space-between"
            alignItems="center"
            align="center"
            xs={12}

By default, each grid item has the same maximum height. You can set the height of the component under the grid item to 100%.

This is an example. https://stackblitz.com/edit/react-8qnvck? File=demo.tsx,MediaControlCard.tsx

In this example, the MediaControlCard component uses the Card and sx properties to set the height to 100%.

If you remove the sx attribute you will see a situation similar to yours.

And I don't think you need to use display:flex in the Box component. Because if you use display:flex, height:100% will not take effect.
