All in a Row

On this card you will learn some tricks for arranging things horizontally on a page. First, you’ll see how to get stuff centered. Then you’ll arrange elements side by side in a row.

  • Add the following CSS properties to the .card class:
margin-left: auto;
margin-right: auto;

You should see the cards move to the center of the page. By setting the left and right margins to auto, you can make any element be in the middle instead of over to the left.

  • Drag the edge of the browser window to make the page narrower and wider — notice that the cards stay centered.

  • Put all of the card links you just made into a new container element. It’s not going to be an article or a section, but one called div. This is a general-purpose container you can use for grouping things and making nice layouts.

<div class="cardContainer">
  • Add the following CSS code in your style sheet:
.cardContainer {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-around;
    padding: 10px;
}

Voilà! Thanks to Flex, your cards are now displayed side by side!

  • Drag the edge of your window to make the website wider and narrower, and watch how the cards move around to fit the window size, sometimes wrapping to the next line.

Cards arranged in two rows spaced evenly to fit the browser width

  • Try deleting the width and height properties from the .card class and see what happens: flex cleverly fits the cards together like a jigsaw puzzle, keeping an even height across everything that’s in the same row.

If you have a navigation menu at the top of your page, that’s another place you can use this trick. Your menu needs to be composed of list elements( (li) for this next bit. If you prefer, you can try it out with my website.

  • Find the CSS rules for the menu. In my website, that’s the blocks nav ul, nav ul li, and nav ul li a.

  • Delete the property display: inline; from the list items. Then, in the list nav ul, add in:

display: flex;
justify-content: flex-start;

Menu with items aligned to the left

You end up with pretty much the same menu, right? The cool thing about flex is you can control the layout with the property justify-content.

  • Change the value of justify-content to flex-end and see what happens. Or change it to space-around to make the menu items evenly spaced, just like you did for the cards.

flex is a pretty powerful layout tool that could fill a whole Sushi Card series of its own — you can learn more about it at dojo.soy/se-flex.
