How to center an element horizontally and vertically

Question

I am trying to center my tabs content vertically, but when I add the CSS style display:inline-flex, the horizontal text-align disappears.

How can I make both text alignments x and y for each of my tabs?

* { box-sizing: border-box; }
#leftFrame {
  background-color: green;
  position: absolute;
  left: 0;
  right: 60%;
  top: 0;
  bottom: 0;
}
#leftFrame #tabs {
  background-color: red;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  height: 25%;
}
#leftFrame #tabs div {
  border: 2px solid black;
  position: static;
  float: left;
  width: 50%;
  height: 100%;
  text-align: center;
  display: inline-flex;
  align-items: center;
}

<div id=leftFrame>
  <div id=tabs>
    <div>first</div>
    <div>second</div>
  </div>
</div>

Answer 1

• Approach 1 - transform translateX/translateY:

  Example Here / Full Screen Example

  In supported browsers (most of them), you can use top: 50%/left: 50% in combination with translateX(-50%) translateY(-50%) to dynamically vertically/horizontally center the element.

.container {
    position: absolute;
    top: 50%;
    left: 50%;
    -moz-transform: translateX(-50%) translateY(-50%);
    -webkit-transform: translateX(-50%) translateY(-50%);
    transform: translateX(-50%) translateY(-50%);
}

<div class="container">
    <span>I'm vertically/horizontally centered!</span>
</div>

---

• Approach 2 - Flexbox method:

  Example Here / Full Screen Example

  In supported browsers, set the display of the targeted element to flex and use align-items: center for vertical centering and justify-content: center for horizontal centering. Just don't forget to add vendor prefixes for additional browser support (see example).

html, body, .container {
    height: 100%;
}

.container {
    display: -webkit-flexbox;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-flex-align: center;
    -ms-flex-align: center;
    -webkit-align-items: center;
    align-items: center;
    justify-content: center;
}

<div class="container"> 
  <span>I'm vertically/horizontally centered!</span>
</div>

---

• Approach 3 - table-cell/vertical-align: middle:

  Example Here / Full Screen Example

  In some cases, you will need to ensure that the html/body element's height is set to 100%.

  For vertical alignment, set the parent element's width/height to 100% and add display: table. Then for the child element, change the display to table-cell and add vertical-align: middle.

  For horizontal centering, you could either add text-align: center to center the text and any other inline children elements. Alternatively, you could use margin: 0 auto, assuming the element is block level.

html, body {
    height: 100%;
}
.parent {
    width: 100%;
    height: 100%;
    display: table;
    text-align: center;
}
.parent > .child {
    display: table-cell;
    vertical-align: middle;
}

<section class="parent">
    <div class="child">I'm vertically/horizontally centered!</div>
</section>

---

• Approach 4 - Absolutely positioned 50% from the top with displacement:

  Example Here / Full Screen Example

  This approach assumes that the text has a known height - in this instance, 18px. Just absolutely position the element 50% from the top, relative to the parent element. Use a negative margin-top value that is half of the element's known height, in this case - -9px.

html, body, .container {
    height: 100%;
}

.container {
    position: relative;
    text-align: center;
}

.container > p {
    position: absolute;
    top: 50%;
    left: 0;
    right: 0;
    margin-top: -9px;
}

<div class="container">
    <p>I'm vertically/horizontally centered!</p>
</div>

---

• Approach 5 - The line-height method (Least flexible - not suggested):

  Example Here

  In some cases, the parent element will have a fixed height. For vertical centering, all you have to do is set a line-height value on the child element equal to the fixed height of the parent element.

  Though this solution will work in some cases, it's worth noting that it won't work when there are multiple lines of text - like this.

.parent {
    height: 200px;
    width: 400px;
    background: lightgray;
    text-align: center;
}

.parent > .child {
    line-height: 200px;
}

<div class="parent">
    <span class="child">I'm vertically/horizontally centered!</span>
</div>

Answer 2

If CSS3 is an option (or you have a fallback) you can use transform:

.center {
    right: 50%;
    bottom: 50%;
    transform: translate(50%,50%);
    position: absolute;
}

Unlike the first approach above, you don't want to use left:50% with the negative translation because there's an overflow bug in IE9+. Utilize a positive right value and you won't see horizontal scrollbars.

Answer 3

The best way to center a box both vertically and horizontally, is to use two containers :

##The outher container :

• should have display: table;

##The inner container :

• should have display: table-cell;
• should have vertical-align: middle;
• should have text-align: center;

##The content box :

• should have display: inline-block;
• should adjust the horizontal text-alignment, unless you want text to be centered

##Demo :

body {
    margin : 0;
}

.outer-container {
    display: table;
    width: 80%;
    height: 120px;
    background: #ccc;
}

.inner-container {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

.centered-content {
    display: inline-block;
    text-align: left;
    background: #fff;
    padding : 20px;
    border : 1px solid #000;
}

<div class="outer-container">
   <div class="inner-container">
     <div class="centered-content">
        Center this!
     </div>
   </div>
</div>

##Centering in the middle of the page:

To center your content in the middle of your page, add the following to your outer container :

• position : absolute;
• width: 100%;
• height: 100%;

Here's a demo for that :

body {
    margin : 0;
}

.outer-container {
    position : absolute;
    display: table;
    width: 100%;
    height: 100%;
    background: #ccc;
}

.inner-container {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

.centered-content {
    display: inline-block;
    text-align: left;
    background: #fff;
    padding : 20px;
    border : 1px solid #000;
}

<div class="outer-container">
   <div class="inner-container">
     <div class="centered-content">
        Center this!
     </div>
   </div>
</div>

Answer 4

Here is how to use 2 simple flex properties to center n divs on the 2 axis:

• Set the height of your container: Here the body is set to be at least 100vh.
• align-items: center will vertically center the blocks
• justify-content: space-around will distribute the free horizontal space around the divs

body {
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: space-around;
}

<div>foo</div>
<div>bar</div>

Answer 5

Run this code snippet and see a vertically and horizontally aligned div.

  width: 100%;
}
.container {
  display: flex;
  align-items: center;
  justify-content: center;
}
.mydiv {
  width: 80px;
}

<div class="container">

</div>

Answer 6

CSS Grid: place-items

Finally, we have place-items: center for CSS Grid to make it easier.

HTML

<div class="parent">
  <div class="to-center"></div>
</div>

CSS

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

Output:

html,
body {
  height: 100%;
}

.container {
  display: grid;
  place-items: center;
  height: 100%;
}

.center {
  background: #5F85DB;
  color: #fff;
  font-weight: bold;
  font-family: Tahoma;
  padding: 10px;
}

<div class="container">
  <div class="center" contenteditable>I am always super centered within my parent</div>
</div>

Answer 7

The simplest and cleanest solution for me is using the CSS3 property "transform":

.container {
  position: relative;
}

.container a {
  position: absolute;
  top: 50%;
  transform: translate(0,-50%);
}

<div class="container">
  <a href="#">Hello world!</a>
</div>

        border: solid 1px black;
        align-items: center;
        justify-content: space-around;
    }
    .align div:first-child {
        width: 20px;
        height: 20px;
        background-color: red;
        position: absolute; 
    }
    .align div {
        width: 20px;
        height: 20px;
        background-color: blue;
    }

        <div></div>
        <div></div>
        <div></div>
    </div>

Another approach is to use table:

<div style="border:2px solid #8AC007; height:200px; width:200px;">
  <table style="width:100%; height:100%">
    <tr style="height:100%">
      <td style="height:100%; text-align:center">hello, multiple lines here, this is super long, and that is awesome, dude</td>
    </tr>
  </table>
</div>

Answer 12

In order to vertically and horizontally center an element we can also use below mentioned properties.

This CSS property aligns-items vertically and accepts the following values:

flex-start: Items align to the top of the container.

flex-end: Items align to the bottom of the container.

center: Items align at the vertical center of the container.

baseline: Items display at the baseline of the container.

stretch: Items are stretched to fit the container.

This CSS property justify-content , which aligns items horizontally and accepts the following values:

flex-start: Items align to the left side of the container.

flex-end: Items align to the right side of the container.

center: Items align at the center of the container.

space-between: Items display with equal spacing between them.

space-around: Items display with equal spacing around them.

<div> I am in the middle</div>

</body>
</html>

Answer 16

You can achieve this using CSS (your element display:inline-grid + grid-auto-flow: row; ) Grid and Flex Box ( parent element display:flex;),

See below snippet

#leftFrame {
  display: flex;
  height: 100vh;
  width: 100%;
}

#tabs {
  display: inline-grid;
  grid-auto-flow: row;
  grid-gap: 24px;
  justify-items: center;
  margin: auto;
}

html,body {
  margin:0;
  padding:0;
}

<div>
<div id=leftFrame>
  <div id=tabs>
    <div>first</div>
    <div>second</div>        
  </div>
</div>
</div>

Answer 17

If you prefer it without:
flexbox / grid / table
or without the:
vertical-align: middle

You can do:

HTML

<div class="box">
  <h2 class="box_label">square</h2>
</div>

CSS

.box {
  box-sizing: border-box;
  width: 100px;
  height: 100px;
  text-align: center;
  border: 1px solid black;
}

.box_label {
  box-sizing: border-box;
  display: inline-block;
  transform: translateY(50%);
  text-align: center;
  border: 1px solid black;
}

Answer 24

The simplest flexbox approach:

The easiest way how to center a single element vertically and horizontally is to make it a flex item and set its margin to auto:

If you apply auto margins to a flex item, that item will automatically extend its specified margin to occupy the extra space in the flex container...

.flex-container {
  height: 150px;
  display: flex;
}

.flex-item {
  margin: auto;
}

<div class="flex-container">
  <div class="flex-item">
    This should be centered!
  </div>
</div>

This extension of margins in each direction will push the element exactly to the middle of its container.
