css align items vertical center with code examples

CSS has many powerful features and one of the most useful is the ability to align items vertically. Aligning items vertically is essential to creating visually stunning designs and makes the content clear and easy to read. In this article, we will explore the different ways of aligning items vertically using CSS, with code examples to help you understand the process.

CSS Vertical Align

CSS vertically aligns elements in two ways: using table cells and through CSS flexbox.

In the past, alignment using table cells was the only method available. However, with CSS flexbox, developers have a much more flexible and powerful method.

CSS Flexbox

Flexbox has revolutionized the way developers style web layouts. With Flexbox, developers can easily align items in a responsive and user-friendly way.

Here is an example of a Flexbox layout:

.container {
   display: flex;
   align-items: center;
}

This code sets up a container with the display: flex property. The align-items: center property then centers the content vertically in the container.

Flexbox has several options for vertical alignment, including:

1. align-items: center centers the items in the container vertically.
2. align-items: flex-start aligns the items to the top of the container.
3. align-items: flex-end aligns the items to the bottom of the container.
4. align-items: stretch stretches the items to the height of the container.
5. align-items: baseline aligns the items to their baseline.

CSS Table Cells

CSS table cells are another way to align items vertically. This method, however, has limitations, as it requires users to ditch divs for tables, or use the display: table property in their CSS code.

Here is an example of how table cells can be used to align items vertically:

.parent {
   display: table-cell;
   vertical-align: middle;
}

This code sets the parent element to a table cell with the display: table-cell property, and the vertical-align: middle property then centers the content vertically.

The table cell method is useful when developers need to align content inside a specific area like a table cell or table-row. However, for a general layout, Flexbox is more flexible and easier to manage.

CSS Tricks

There are other CSS tricks to achieve vertical alignment without Flexbox. Let's take a look at a few of them.

1. line-height – Setting the line-height property of the parent element equal to the height of the container can vertically align the text like this:

.parent {
   height: 100px;
   line-height: 100px;
}

2. absolute – Using the position: absolute; property can help center non-text items in the container:

.parent {
   position: relative;
}
.child {
   position: absolute;
   top: 50%;
   transform: translate(0, -50%);
}

3. CSS Grid – Using grid is yet another simple method of achieving vertical alignment.

.container {
  display: grid;
  place-items: center;
}

This code sets up the container as a CSS grid with place-items: center property which centers items horizontally and vertically.

Conclusion

In conclusion, CSS has many powerful tools to align items vertically. Developers can use table cells in CSS, CSS flexbox, or other CSS tricks and hacks for vertical alignment of elements. Although Flexbox is the preferred method of aligning items these day, it is essential to understand the other techniques lest any of them be useful in the future.

As a developer, it's essential to experiment with these techniques to find the best solution for your needs. With these tips and tricks in hand, you are well on your way to create amazing designs that are both beautiful and functional.

Sure! Let's explore CSS Flexbox in more detail and look at some code examples.

CSS Flexbox

Flexbox is an incredibly powerful tool for aligning items in a container. In Flexbox, the container is also called the flex container, and the items inside are called flex items. The flex container is made using the display: flex property.

.container {
   display: flex;
}

This code creates a container using display: flex. Now, the child elements within this container can be aligned as desired.

The first step to aligning elements vertically is to use the align-items property. This property controls how the items are aligned along the y-axis. There are five options available:

1. align-items: flex-start aligns the items to the start of the container.
2. align-items: flex-end aligns the items to the end of the container.
3. align-items: center centers the items vertically within the container.
4. align-items: stretch stretches the items to fill the container height.
5. align-items: baseline aligns the items along their baseline.

For example, if we want to align the items to the center of the container, we can use the following code:

.container {
   display: flex;
   align-items: center;
}

This code aligns the items vertically in the center of the container.

Next, we can use the justify-content property to control how the items are aligned horizontally. This property has different options as well:

1. justify-content: flex-start aligns the items to the start of the container.
2. justify-content: flex-end aligns the items to the end of the container.
3. justify-content: center centers the items horizontally within the container.
4. justify-content: space-between spreads the items apart with equal space on either side of each item.
5. justify-content: space-around spreads the items apart with equal space around each item.
6. justify-content: space-evenly spreads the items apart with equal space between and around each item.

For example, let's justify the items using the space-evenly option.

.container {
   display: flex;
   align-items: center;
   justify-content: space-evenly;
}

This code will distribute the items equally within the container, with equal space around each item.

CSS Flexbox Properties

Now, let's explore some of the other properties you can manipulate in Flexbox.

1. flex-direction: You can control the direction of the flex container with this property. There are four options available— row (default), row-reverse, column, and column-reverse.

2. flex-wrap: This property allows you to wrap the items in the container. There are three options available— nowrap (default), wrap, and wrap-reverse.

3. flex-flow: This shorthand property allows you to set flex-direction and flex-wrap together.

4. align-content: This property controls the alignment of the items on the cross-axis (y-axis) when there is extra space in the container. These options work similarly to justify-content.

Code Example

Here's an example of how to use these properties together:

.container {
   display: flex;
   flex-direction: column;
   flex-wrap: wrap;
   align-items: center;
   justify-content: space-evenly;
   align-content: center;
}

This code creates a container with a column direction, wrap, and aligns the items horizontally in the center of the container. It then justifies the items with equal space on either side of each item. Lastly, it aligns the items in the center of the container along the y-axis.

In Conclusion

CSS Flexbox is a powerful tool for aligning items vertically and horizontally in a container. With multiple properties available, developers can create responsive and user-friendly designs effortlessly. Using the flexbox technique, the layout of a page can be easily achieved across all device types from desktop to mobile. It's essential to understand the different properties to make the best use of this technique. So, give it a try and let it revolutionize the way your webpage appears!
