`justify-content` is a CSS property that allows us to align flex items along the main axis of a flex container. The `justify-content` property has several values that can be used to control how flex items are positioned within a flex container. In this article
we will explore the different values of the `justify-content` property and how they can be used in practice.
The main axis of a flex container is determined by the `flex-direction` property. If the `flex-direction` property is set to `row`
then the main axis runs horizontally from left to right. If the `flex-direction` property is set to `column`
then the main axis runs vertically from top to bottom.
The `justify-content` property accepts the following values:
1. `flex-start`: This value aligns flex items at the start of the main axis of the flex container. For a flex container with a `flex-direction` of `row`
this will align items at the left edge of the container. For a flex container with a `flex-direction` of `column`
this will align items at the top of the container.
2. `flex-end`: This value aligns flex items at the end of the main axis of the flex container. For a flex container with a `flex-direction` of `row`
this will align items at the right edge of the container. For a flex container with a `flex-direction` of `column`
this will align items at the bottom of the container.
3. `center`: This value aligns flex items at the center of the main axis of the flex container. This will center the items both horizontally and vertically within the container.
4. `space-between`: This value distributes flex items evenly along the main axis of the flex container
with the first item aligning at the start of the axis and the last item aligning at the end of the axis. The space between each item is equal.
5. `space-around`: This value distributes flex items evenly along the main axis of the flex container
with equal space around each item. This means that there will be space between each item as well as space on the outer edges of the container.
6. `space-evenly`: This value distributes flex items evenly along the main axis of the flex container
with equal space between each item as well as on the outer edges of the container.
These values can be applied to a flex container using the following syntax:
```css
.container {
display: flex;
justify-content: value;
}
```
Let's take a look at some examples to see how the `justify-content` property works in practice.
Example 1: `flex-start`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `flex-start`. This will align the items at the start of the main axis
which is the left edge of the container.
```css
.container {
display: flex;
justify-content: flex-start;
}
```
Example 2: `flex-end`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `flex-end`. This will align the items at the end of the main axis
which is the right edge of the container.
```css
.container {
display: flex;
justify-content: flex-end;
}
```
Example 3: `center`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `center`. This will align the items at the center of the main axis
both horizontally and vertically.
```css
.container {
display: flex;
justify-content: center;
}
```
Example 4: `space-between`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `space-between`. This will distribute the items evenly along the main axis
with the first item aligning at the start of the axis and the last item aligning at the end.
```css
.container {
display: flex;
justify-content: space-between;
}
```
Example 5: `space-around`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `space-around`. This will distribute the items evenly along the main axis
with equal space around each item.
```css
.container {
display: flex;
justify-content: space-around;
}
```
Example 6: `space-evenly`
In this example
we have a flex container with a `flex-direction` of `row` and a `justify-content` value of `space-evenly`. This will distribute the items evenly along the main axis
with equal space between each item as well as on the outer edges of the container.
```css
.container {
display: flex;
justify-content: space-evenly;
}
```
In conclusion
the `justify-content` property in CSS is a powerful tool for controlling the alignment of flex items within a flex container. By using the different values of the `justify-content` property
you can create a wide range of layouts and designs that are responsive and flexible. I hope this article has helped you understand how the `justify-content` property works and how you can use it in your own CSS projects.
