# Horizontal & Vertical Align

https\://www\.w3schools.com/css/css\_align.asp

### Center Align Elements

To horizontally center a block element (like \<div>), use `margin: auto;`

Setting the width of the element will prevent it from stretching out to the edges of its container.

The element will then take up the specified width, and the remaining space will be split equally between the two margins:

.center { margin: auto; width: 50%; border: 3px solid green; padding: 10px; }

### Center Align Text

To just center the text inside an element, use `text-align: center;`

.center { text-align: center; border: 3px solid green; }

### Center an Image

To center an image, set left and right margin to `auto` and make it into a `block` element:

img { display: block; margin-left: auto; margin-right: auto; width: 40%; }

### Left and Right Align - Using position

One method for aligning elements is to use `position: absolute;`:

.right { position: absolute; right: 0px; width: 300px; border: 3px solid #73AD21; padding: 10px; }

### Left and Right Align - Using float

Another method for aligning elements is to use the `float` property:

.right { float: right; width: 300px; border: 3px solid #73AD21; padding: 10px; }

Then we can add `overflow: auto;` to the containing element to fix this problem

.clearfix { overflow: auto; }

### Center Vertically - Using padding

There are many ways to center an element vertically in CSS. A simple solution is to use top and bottom `padding`:

.center {\
&#x20; padding: 70px 0;\
&#x20; border: 3px solid green;\
}

To center both vertically and horizontally, use `padding` and `text-align: center`:

.center { padding: 70px 0; border: 3px solid green; text-align: center; }

### Center Vertically - Using line-height

Another trick is to use the `line-height` property with a value that is equal to the `height` property:

.center { line-height: 200px; height: 200px; border: 3px solid green; text-align: center; }

&#x20;.center p { line-height: 1.5; display: inline-block; vertical-align: middle; }

### Center Vertically - Using position & transform

If `padding` and `line-height` are not options, another solution is to use positioning and the `transform` property

.center { height: 200px; position: relative; border: 3px solid green; }

.center p { margin: 0; position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); }

### Center Vertically - Using Flexbox

You can also use flexbox to center things. Just note that flexbox is not supported in IE10 and earlier versions:

.center { display: flex; justify-content: center; align-items: center; height: 200px; border: 3px solid green; }
