css align text in middle of screen code example

Example 1: html center body

body {
  display:flex; flex-direction:column; justify-content:center;
  min-height:100vh;
}

Example 2: css center position

/**************** 1º method to center all elements ********************/
body {                   
  text-align: center;
}

/* If all of your elements have the property display equal to "inline", 
"block" or "inline-block", then you can use the text-align: center in
the <body> tag */

tag_name {
    display: inline; /* block or inline-block*/
}

/*...but if we have an element of type "block" with a width diferente
from the default (maximum width of the page), then this will no 
longer work!*/
  
tag_name {
    display: block;
  	width: 170px;
}


/**************** 2º method to center all elements ********************/
/* Another method, is to use the margins to center the element 
horizontally and/or vertically */

tag_name {
    display: block;
  	width: 100px;
  	margin: 0 auto 0 auto;  /* top, right, bottom, left */
}

Example 3: center element in div

/* html */
<h1>Centering with CSS</h1>

<h3>Text-Align Method</h3>
<div class="blue-square-container">
  <div class="blue-square"></div>
</div>

<h3>Margin Auto Method</h3>
<div class="yellow-square"></div>

<h3>Absolute Positioning Method</h3>
<div class="green-square"></div>

/* css */
h1,
h3 {
  text-align: center;
}

.blue-square-container {
  text-align: center;
}

.blue-square {
  background-color: #0074D9;
  width: 100px;
  height: 100px;
  display: inline-block;
}

Example 4: how to center div

<!DOCTYPE html>
<!--clearfix-->
<html>
<head>
<style>
div {
  border: 3px solid #4CAF50;
  padding: 5px;
}

.img1 {
  float: right;
}

.clearfix {
  overflow: auto;
}

.img2 {
  float: right;
}
</style>
</head>
<body>

<p>In this example, the image is taller than the element containing it, and it is floated, so it overflows outside of its container:</p>

<div>
  <img class="img1" src="pineapple.jpg" alt="Pineapple" width="170" height="170">
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum...
</div>

<p style="clear:right">Add a clearfix class with overflow: auto; to the containing element, to fix this problem:</p>

<div class="clearfix">
  <img class="img2" src="pineapple.jpg" alt="Pineapple" width="170" height="170">
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Phasellus imperdiet, nulla et dictum interdum...
</div>

</body>
</html>
