Why I'm not able to see my cards as flex or grid layout?

I actaually made cards for my team members, and the cards went well but the layout is problematic. I tried with both CSS Flexbox and CSS3 Grid, my browser supports both of them but though I'm facing. And this works very well in mobile!!

I tried flex: 2 0 100%;

and also display: grid; grid-template-columns: repeat(470px, 1fr); grid-auto-rows: auto; grid-gap: 1em;

Is there any solution for this problem?

.cards2 {
    font-size: 11px;
    width: 100%;
    height: auto;
    padding: 1em 0;
}

.cards2 a { text-decoration: none; }

.cards2 .container {
    display: grid;
    grid-template-columns: repeat(470px, 1fr);
    grid-auto-rows: auto;
    grid-gap: 1em;
}
