One of the more interesting challenges of creating a layout is: how can we lay out columns that stretch downward so that they are the same height without using tables? This problem is related to the behavioral features of the block model, and it is illustrated in the images below:
There are several techniques for solving this problem, which are described in this article. By the way, we also borrowed these images from that article.
Let’s apply a gradient trick with sharp transitions that simulate stretched columns. Backgrounds that utilize these types of gradients are usually placed in a container of columns. The proportions of the gradients are selected to match the proportions of the columns so that they stretch the same.
The effect shown in the assignment can be more easily achieved with flexboxes.

class="course-theory__content-text"><p>One of the more interesting challenges of creating a layout is: how can we lay out columns that stretch downward so that they are the same height without using tables? This problem is related to the behavioral features of the block model, and it is illustrated in the images below:</p><p class="grid grid--gutters"><span class="grid__cell"><img width="250" src="/assets/courses/40/columns-problem.png" alt="The problem has to do with the behavior of the blocks in the layout."></span><span class="grid__cell"><img style="margin-left:20px;" width="250" src="/assets/courses/40/columns-desire.png" alt="Desired behavior of blocks in the layout"></span></p><p>There are several techniques for solving this problem, which are described in <a href="http://css-tricks.com/fluid-width-equal-height-columns" target="_blank" rel="nofollow">this article</a>. By the way, we also borrowed these images from that article.</p><p>Let’s apply a gradient trick with sharp transitions that simulate stretched columns. Backgrounds that utilize these types of gradients are usually placed in a container of columns. The proportions of the gradients are selected to match the proportions of the columns so that they stretch the same.</p><p class="info info--gray">The effect shown in the assignment can be more easily achieved with <a href="/courses/layout/flexbox-1/flexbox-vertical-align">flexboxes</a>.</p></div></div><div class="js--theory-pane__comments hidden course-theory__content-inner"><div class="course-theory__content-text"><h2 class="course-theory__content-heading">Comments</h2><div id="disqus_thread"></div><script>
