![]() If we would like to set up elements like in the vertical column, we can do it as well. If we would like to justify our elements, we need to add a similar property like in the previous example, but instead of the center we are using method space-between, so our property should look like justify-content: space-between ![]() If we would like to do center our elements in the horizontal position, we need to add property justify-content: center to our container. What I use very often, and it’s much more challenging to set up without flex, is centering content to the container. How to align content to center horizontally We can align our elements to the right by specifying a container’s property flex-direction: row-reverse.ģ. This time we align content to the right side of the container. We can align our elements to the left by specifying a container’s property flex-direction: row.Īs in the previous example, we align content to the one side. Very often, we would like to set up our content on the one side of the page, and it’s a bit similar to the float left, but not 100% the same. Let’s see a few most critical elements of flexbox which we can use in our daily work. In this article, I would like to explain what flexbox is and how we can use it to save a lot of our time.įlexbox is a CSS layout module that allows us to setup nice-behaving and responsive grid in a speedy and friendly way. Probably almost everybody in the front-end industry heard something about the flexbox and benefits which it can give to us when we need to design a grid. How to fulfill the whole container’s height with items (stretch) How to vertically and horizontally align-center elements (align-items: center) How to setup elements on the bottom of the container (align-items:flex-end) How to setup elements on top of the container (align-items:flex-start) This article is excerpted from Unleashing the Power of CSS: Advanced Techniques for Responsive User Interfaces, available on SitePoint Premium. Heydon Pickering’s and Andy Bell’s sidebar layout, which shows how to force varying Flexbox-based breakpoints for better control of when items wrap.Heydon Pickering’s Flexbox Holy Albatross, which breaks down from columns into a single row based on the parent container’s total width.Here are two other Flexbox techniques that use flex-grow and flex-basis in interesting ways: Responsive Flexbox Grid layout – adjusted –min by SitePoint ( CodePen. Here’s a CodePen demo of this code in action. The other list children in this example will still flow around it and use the 30ch from the base rule, but the wider column effectively changes the behavior. Since we’re setting that value via the -min custom property, and Flexbox children control their own size, we can adjust it with an inline style. The flex-basis property can be further adjusted for this solution to assign unique “breakpoints” for different items. Responsive Flexbox Grid layout by SitePoint ( CodePen. The following CodePen demo shows our Flexbox layout in action. (Experiment with the CodePen demo below.) It’s important to keep flex-shrink to 1, so that, eventually - when the available inline space is narrower than the flex-basis - the items are still allowed to “shrink”, as this helps to prevent overflow. The flex shorthand sets, in order, flex-grow, flex-shrink, and flex-basis.Īs an experiment, we can change the flex-grow value to 0 and see how the items will only expand up to the flex-basis value. For Flexbox, we set the child layout behavior on the children. Keen readers may have noticed another key difference between these solutions: when using Grid, the parent defines the child behavior. Note: in both the Grid and Flexbox solutions, if we add a gap, that space will be subtracted from the calculation of how many columns may be created before new rows are added. The image below shows the final, odd-numbered list item spanning two columns, thanks to the flex-grow property. It therefore has a similar behavior to 1fr in most cases. If we have three items and the third needs to move to a new row, it will take up the remaining space due to the flex shorthand, which importantly sets flex-grow to 1. In this code, as in the Grid code, the browser will create as many columns as will fit the inline space with at least the -min size of 30ch. With Flexbox, we can direct the flex items to grow to fill all remaining extra space, preventing an “orphan” that appears with the Grid solution. The difference between the Flexbox and Grid solution is that grid items that flow to a new row can’t expand across multiple grid columns. ![]() We can accomplish a similar experience with Flexbox.
