css flexbox

the combined widths of all the flex items within it.

Items shrink when the width of the parent container is smaller than

justify-content: center;

There are several options for how to space the flex items along the line that is the main axis. One of the most commonly used is which aligns all the flex items to the center inside the flex container.

flex property

There is a shortcut available to set several flex properties at once. The flex-grow, flex-shrink, and flex-basis properties can all be set together by using the

flex-shrink

When it's used, it allows an item to shrink if the flex container is too small

align-self

accepts the same values as align-items and will override any value set by the align-items property.

center

align items to the center. For rows, this vertically aligns items (equal space above and below the items). For columns, this horizontally aligns them (equal space to the left and right of the items).

baseline

align items to their baselines. Baseline is a text concept, think of it as the line that the letters sit on.

space-between:

aligns items to the center of the main axis, with extra space placed between the items. The first and last items are pushed to the very edge of the flex container

flex-end:

aligns items to the end of the flex container. For a row, this pushes the items to the right of the container. For a column, this pushes the items to the bottom of the container.

flex-end

aligns items to the end of the flex container. For rows, this aligns items to the bottom of the container. For columns, this aligns items to the right of the container.

flex-start:

aligns items to the start of the flex container. For a row, this pushes the items to the left of the container. For a column, this pushes the items to the top of the container. This is the default alignment if no

flex-start

aligns items to the start of the flex container. For rows, this aligns items to the top of the container. For columns, this aligns items to the left of the container.

flex containers

also have a cross axis which is the opposite of the main axis. For rows, the cross axis is vertical and for columns, the cross axis is horizontal.

vertically

creating a column using flex direction will align the children

align-self

his property allows you to adjust each item's alignment individually, instead of setting them all at once.

flex-basis

property are the same as other size properties (px, em, %, etc.). The value auto sizes items based on the content.

flex-grow

property controls the size of items when the parent container expands. and is the opposite of flex-shrink

align-items

property is similar to justify-content. Recall that the justify-content property aligned flex items along the main axis. For rows, the main axis is a horizontal line and for columns it is a vertical line.

order

property is used to tell CSS the order of how flex items appear in the flex container

flex-basis

property specifies the initial size of the item before CSS makes adjustments with flex-shrink or flex-grow.

flex-wrap

property tells CSS to wrap items. This means extra items move into a new row or column. The break point of where the wrapping happens depends on the size of the items and the size of the container.

space-around:

similar to space-between but the first and last items are not locked to the edges of the container, the space is distributed around all the items with a half space on either end of the flex container.

strecth

stretch the items to fill the flex container. For example, rows items are stretched to fill the flex container top-to-bottom. This is the default value if no align-items value is specified.

main axis

the direction the flex items are arranged is called the

nowrap

this is the default setting, and does not wrap items.

wrap

wraps items from left-to-right if they are in a row, or top-to-bottom if they are in a column.

wrap=reverse

wraps items from right-to-left if they are in a row, or bottom-to-top if they are in a column.

visual elements , placement or positioning of those elements

A website's User Interface ("UI") has two components

display: flex;

Add the CSS property display to #box-container and set its value to flex. #box-container { height: 500px; }

#box-1 {flex: 2 2 150px; background-color: dodgerblue; height: 200px; } #box-2 {flex:1 1 150px; background-color:

Add the CSS property flex to both #box-1 and #box-2. Give #box-1 the values so its flex-grow is 2, its flex-shrink is 2, and its flex-basis is 150px. Give #box-2 the values so its flex-grow is 1, its flex-shrink is 1, and its flex-basis is 150px. These values will cause #box-1 to grow to fill the extra space at twice the rate of #box-2 when the container is greater than 300px and shrink at twice the rate of #box-2 when the container is less than 300px. 300px is the combined size of the flex-basis values of the two boxes. #box-1 { background-color: dodgerblue; height: 200px; } #box-2 { background-color: orangered;

horizontal

Creating a row using flex direction will align the children

space-evenly:

Distributes space evenly between the flex items with a full space at either end of the flex container

to build a responsive page

Placing the CSS property display: flex; on an element allows you to use other flex properties

row

The default value for the flex-direction property is

flex-start, flex-end, center, streched, baseline

The different values available for align-items include:

numbers as values

The flex-shrink property takes

flex direction property

This makes it possible to align any children of that element into rows or columns. You do this by adding the
