javascript - Arrange multiple divs in CSS/JS?

Question

Currently I have these divs using MDB

    <div class="row" style="margin-top: 8em;">

            <div class="col-md-6">
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-default"><b>Project 1</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-default"><b>86%</b></h1>
                        </div>
                    </div>
                </div>
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-primary"><b>Project 2</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-primary"><b>86%</b></h1>

                </div>
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-secondary"><b>Project 3</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-secondary"><b>86%</b></h1>
                        </div>
                    </div>
                </div>
            </div>
            <div class="col-md-6">
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-success"><b>Project 4</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-success"><b>86%</b></h1>
                        </div>
                    </div>
                </div>
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-danger"><b>Project 5</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-danger"><b>86%</b></h1>
                        </div>
                    </div>
                </div>
                <div class="rounded-rectangle-svs card current-proj">
                    <h5 class="text-warning"><b>Project 6</b></h5>
                    <div class="row" style="overflow-x:auto;">
                        <div class="col-md-8">
                            <p class="">Lorem Ipsum is simply dummy text of the printing and typesetting industry. </p>
                        </div>
                        <div class="col-md-4 text-center">
                            <h1 class="text-warning"><b>86%</b></h1>
                        </div>
                    </div>
                </div>
            </div>
    </div>

and the output of these divs is like this

As you can see the 2 different div with the class name of col-md-6 is inside the row div.

for each col-md-6 contains 3 different projects.

What I'm trying to do, is it possbile to arrange these divs of projects without using col-md-6? with just JavaScript? with the arrangement like that too?

Because those project will be coming from my database it's a bad idea to use col-md-6 for this situation that's why I'm trying to do the automatic arrangement of divs with two(2) columns like that even if I loaded multiple divs. It will rearrange just like that

Answer 1

Take a look at Bootstraps card layout card-deck. You can fill a single div with x amount of cards. The width of each card can be declared in CSS by flex-basis.

This way there's no need for extra columns to make it responsive. Also no need to create a mapping when using CSS-grid (which is also a valid solution). No need for JavaScript solutions.

Below I've extended the card-deck layout with two-col class. Similarly you can extend to three-col or four-col and so on.

SCSS

.card-deck {
    .card {
        flex-basis: 100%; // mobile first
    }

    /*@media (min-width: 768px)*/
    @include media-breakpoint-up(md) {
        &.two-col {
            .card {
                flex-basis: calc(50% - #{$grid-gutter-width}); // -30px
            }
        }
    }        
}
