问题
I'm trying to create flex box columns for web development. However, all I managed to do is produce one column of flex boxes.
What are some basic CSS codes that would verify that the div cards always fill up the page grid and that for a width small enough, the contents are laid out in a single column.
@charset "utf-8";
/*
CSS Code
*/
section {
display: flexbox;
flex-direction: row;
flex-wrap: wrap-reverse;
}
div.card {
display: flex;
flex-basis: 200px;
flex-grow: 1;
flex-shrink: 1;
flex-direction: column;
flex-wrap: nowrap;
justify-content: space-between;
align-items: center;

On your section CSS, change flexbox to flex and it shall work.
@charset "utf-8";
/*
CSS Code
*/
section {
display: flex; /* Change from flexbox to flex */
flex-direction: row;
flex-wrap: wrap-reverse;
}
div.card {
display: flex;
flex-basis: 200px;
flex-grow: 1;
flex-shrink: 1;
flex-direction: column;
flex-wrap: nowrap;
justify-content: space-between;
align-items: center;
