问题:

I\'m trying to do a layout with bootstrap, but I can\'t figure it out what I\'m doing wrong. I\'m putting two columns of 6 and the second column of 6 I\'m putting 2 columns of 3 inside, but it\'s not working. I\'m new to bootstrap.

Here is the code:

<!DOCTYPE html>

You\'re just missing a basic Bootstrap \"rule\". From the docs..

In a grid layout, content must be placed within columns and only columns may be immediate children of rows.

In Bootstrap 4, .col- that are not placed in .row will stack vertically.

<div class=\"row\">
    <div class=\"col-12 col-sm-12 col-md-6 col-xl-6\" style=\"border-left: solid 1px #ffbfbf;\">
        <div style=\"height: 700px; background-color: #FF3355; border-radius: 15px;\">a a a a a a</div>
    </div>
    <div class=\"col-12 col-sm-12 col-md-6 col-xl-6\" style=\"border-left: solid 1px #ffbfbf;\">
        <div class=\"row\">
            <div class=\"col-12 col-sm-12 col-md-6 col-xl-6\" style=\"padding-right: 0px; padding-left:0px;border-left: solid 1px #ffbfbf;\">
