Pen Settings

CSS Base

Vendor Prefixing

Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

              <div class="paddingBlock">
  <h1>EQUAL HEIGHT COLUMNS</h1>
  <p>Simply add display:flex to the parent</p>
  <div class="equalHWrap eqWrap">
    <div class="equalH eq">boo <br> boo</div>
    <div class="equalH eq">shoo</div>
    <div class="equalH eq">clue</div>
  </div>
</div>            

<div class="paddingBlock">
  <h1>EQUAL HEIGHT + WIDTH COLUMNS</h1>
  <p>Add display:flex to the parent and flex:1 to the boxes</p>
  <div class="equalHWrap eqWrap">
    <div class="equalHW eq">boo <br> boo</div>
    <div class="equalHW eq">shoo</div>
    <div class="equalHW eq">clue</div>
  </div>
</div>            

<div class="paddingBlock">
  <h1>EQUAL HEIGHT + WIDTH COLUMNS WITH MARGINS</h1>
  <p>Add display:flex, justify-content: space-between; to the parent and give a width to the boxes that totals to less than 100%. E.g. These boxes have a width of 32% each. The remaining width of 4% (i.e. 32 x 3 = 96%) will be used to create the space between the boxes and simulate margins. No need to remove margins on the first and last child!</p>
  <div class="equalHMWrap eqWrap">
    <div class="equalHM eq">boo <br> boo</div>
    <div class="equalHM eq">shoo</div>
    <div class="equalHM eq">clue</div>
  </div>
</div>

<div class="paddingBlock">
  <h1>EQUAL HEIGHT COLUMNS WITH MARGINS IN MULTIPLE ROWS</h1>
  <p>Building on the above example, just give bottom margins to the boxes. Add a flex-wrap: wrap to the parent, so that boxes go to the next line when they run out of space in a 'row'.</p>
  <div class="equalHMRWrap eqWrap">
    <div class="equalHMR eq">boo</div>
    <div class="equalHMR eq">shoo</div>
    <div class="equalHMR eq">clue</div>
    <div class="equalHMR eq">boo <br> boo </div>
    <div class="equalHMR eq">shoo</div>
    <div class="equalHMR eq">clue</div>
  </div>
</div>

<div class="paddingBlock">
  <h1>EQUAL HEIGHT COLUMNS WITH MARGINS IN MULTIPLE ROWS and VARIABLE NO OF BOXES</h1>
  <p>Add display:flex, flex-wrap: wrap to the parent and give a width to the boxes. Give margins to the boxes and remove the left and right margins of the first and last box in each 'row' using the nth-of-type selector. Unlike the previous example, justify-content: space-between on the parent does not work for an uneven number of boxes, because if there are five boxes in all, the third and fifth will align to the left and right of the perceived 'row'.</p>
  <div class="equalHMVWrap eqWrap">
    <div class="equalHMV eq">boo <br> boo</div>
    <div class="equalHMV eq">shoo</div>
    <div class="equalHMV eq">clue</div>
    <div class="equalHMV eq">boo <br> boo </div>
    <div class="equalHMV eq">clue</div>
  </div>
</div>
