# Flex-Grow
|
|
|
|
The flex-grow property is a flexbox property that allows you to specify the allocation of free space to containers within a flex-container. It provides a solution to all that unwanted space!
|
|
|
|
It'll turn your container from this

What just happened?
|
|
|
|
Well, we added two things to the css syntax.
|
|
|
|
HTML
|
|
|
|
```html
|
|
<p class = "ten">1</p>
|
|
<p class = "twenty">2</p>
|
|
```
|
|
|
|
CSS
|
|
|
|
```css
|
|
body {
|
|
display:flex;
|
|
}
|
|
|
|
p {
|
|
flex-grow: 1;
|
|
}
|
|
```
|
|
|
|
Two things happened
|
|
|
|
1. The parent container was converted into a flex-display by `display:flex`
|
|
2. The remaining "free space" was then allocated among the remaining p containers in an equal ration since each has a flex-grow property of 1.
|
|
|
|
What happens if we have p containers with different flex-grow properties?
|
|
|
|
Let's see an example.
|
|
|
|
First let's create two paragraphs and enable display: flex;
|
|
|
|

|
|
|
|
Notice a few things
|
|
|
|
- The colour scheme is nice
|
|
- There's some empty space to the right of the two boxes.
|
|
|
|
That empty space is the "free space" that will be allocated to each of the different paragraphs later depending on their flex-grow properties.
|
|
|
|
To see this in action, let's give the first one a class of "ten" and a flex-grow property of 1. Let's also give the second one a class of "twenty" and a flex-grow property of 2.
|
|

|

|
|
|
|
Notice a few things
|
|
|
|
1. The second one's size is not double that of the first one despite having a flex-grow property that is double that of the first.
|
|
2. The entire space is filled. ( Some margins were added to the side to enable it to be seen more clearly. )
|
|
|
|
As we resize the screen, we also find that the first one shrinks at twice the speed of the second one.
