The result of this is that your items will all line up in a row, using the size of the content as their size in the main axis. If there are more items than can fit in the container, they will not wrap but will instead overflow. If some items are taller than others, all items will stretch along the full length of the cross-axis. The justify-content property is used to align the items on the main axis, the direction in which flex-direction has set the flow. The initial value is flex-start which will line the items up at the start edge of the container, but you could also set the value to flex-end to line them up at the end, or center to line them up in the center. You can also use the value space-between to take all the spare space after the items have been laid out, and share it out evenly between the items so there will be an equal amount of space between each item. To cause an equal amount of space on the right and left of each item use the value space-around. With space-around, items have a half-size space on either end. Or, to cause items to have equal space around them use the value space-evenly. With space-evenly, items have a full-size space on either end. The live example below allows you to test out the different values of the flex shorthand; remember that the first value is flex-grow. Giving this a positive value means the item can grow. The second is flex-shrink — with a positive value the items can shrink, but only if their total values overflow the main axis. The final value is flex-basis; this is the value the items are using as their base value to grow and shrink from. Today I’m sharing the details on my new FLEX tool boxes, plus more exciting equipment. FLEX Tool Boxes & More

The flex-wrap property is set to nowrap. This means that the flex items will always remain in a single row or column, overflowing their container if their combined width/ height exceeds the containing element width/ height. Flexbox ignores overflow: hidden and expands the flexbox child when the content is larger than the child’s width. In both cases the start edge of the cross-axis is at the top of the flex container and the end edge at the bottom, as both languages have a horizontal writing mode.Using flex: auto is the same as using flex: 1 1 auto; everything is as with flex:initial but in this case the items can grow and fill the container as well as shrink if required. If the flex-direction is row and I am working in English, then the start edge of the main axis will be on the left, the end edge on the right. An area of a document laid out using flexbox is called a flex container. To create a flex container, we set the value of the area's container's display property to flex or inline-flex. As soon as we do this the direct children of that container become flex items. As with all properties in CSS, some initial values are defined, so when creating a flex container all of the contained flex items will behave in the following way. You can add a :after pseudo element in container with the placeholder button. It has the effect as flex: 999 999 auto which consumes all space in the last line of your content. More Stuffs Before we can make sense of these properties we need to consider the concept of available space. What we are doing when we change the value of these flex properties is to change the way that available space is distributed amongst our items. This concept of available space is also important when we come to look at aligning items.

tl;dr - We don't provide testing for attributes that works over single item basis. What is the :after placeholder? You can read more about the relationship between flexbox and the Writing Modes specification in a later article; however, the following description should help explain why we do not talk about left and right and top and bottom when we describe the direction that our flex items flow in. Using flex: none will create fully inflexible flex items. It is as if you wrote flex: 0 0 auto. The items cannot grow or shrink but will be laid out using flexbox with a flex-basis of auto.If you set box-flex to 0, Firefox forces the element to act like it’s using the quirks-mode box model. Features: Fold-down shelf creates discrete storage option that is great for small or crowded workshops. 70 lb. carrying capacity. The shorthand you often see in tutorials is flex: 1 or flex: 2 and so on. This is as if you used flex: 1 1 0 or flex: 2 1 0 and so on, respectively. The items can grow and shrink from a flex-basis of 0. The flex-basis property is set to auto. This means that, in each case, it will be equal to the flex item width in horizontal writing mode, and the flex item height in vertical writing mode. If the corresponding width/ height is also set to auto, the flex-basis content value is used instead.
