Learn about flex auto margins here: Methods for Aligning Flex Items (see box#56). When flex items are stacked vertically: #container The height of the centered divs doesn't matter. In both cases the height of the centered divs can be variable, undefined, unknown, whatever. One for vertically-aligned flex items ( flex-direction: column) and the other for horizontally-aligned flex items ( flex-direction: row). How to Center Elements Vertically and Horizontally in Flexboxīelow are two general centering solutions. row container is not needed unless you want to add some styling around the elements (background image, borders and so on).

The flex-flow, flex-direction, flex-wrap properties could have made this design easier to implement. flex-container needs a height to see the vertical alignment effect, otherwise, the container computes the minimum height needed to enclose the content, which is less than the view port height in this example. row to be centered vertically in the view port, assign 100% height to html and body, and also zero out the body margins. row, set the width to auto instead of 100%. flex-item elements should be block level ( div instead of span) if you want the height and top/bottom padding to work properly.Īlso, on. Justify-self and align-items properties should be used for the child of the parent element, if need be.Your. So also justify-content and align-items properties. If set to column then the justify-content property will effect on the vertical plane while the align-items property will effect on the horizontal plane but if set to row then reverse is the case for the justify-content and align-items properties.įlexbox should be used on the parent element alone. The flex-direction property will determine what plane the justify-content and align-items properties will take effect. Then, the align-items: center property will center the container element on the horizontal plane (as against the vertical plane when it the flex-direction was set to row). Since column favours the vertical plane, when you set the the flex-direction: column, the justify-content: center property centers the container element along the vertical plane (no longer the horizontal plane as it was when the flex-direction was set to row).
