The center() function is used to set the alignment of element into the center either vertically, horizontally, or both, relative to its parent element or according to the body if the element has no parent. If this function does not contain any parameters then the element will align both vertically and horizontally.
Note: This function requires the p5.dom library. So add the following line in the head section of the index.html file.
<script language="javascript"Â Â Â Â type="text/javascript" src="path/to/p5.dom.js"> </script> |
Syntax:
center( align )
Parameters: This function accepts single parameter align which holds the string ‘vertical’ or ‘horizontal’ to align the element.
Below examples illustrate the center() function in p5.js:
Example 1:
function setup() {           // Create canvas of given size     createCanvas(1000, 200);           // Set background color     background('green');           var div = createDiv('').size(200, 70);           div.html('Welcome to neveropen', true);           // Set the position of div into center     div.center();         // Set font-size of text     div.style('font-size', '24px');         // Set font-color of text     div.style('color', 'white');         div.style('border', '1px solid white');         div.style('text-align', 'center');   } |

Example 2:
function setup() {           // Create canvas of given size     createCanvas(1000, 200);           // Set background color     background('green');           // Create an input element     var input_val = createInput('');              // Set the attribute and its value        input_val.attribute('value', 'Welcome to neveropen');             // Set the position of div into center     input_val.center();         // Set font-size of text     input_val.style('font-size', '24px');           // Set the width of input area     input_val.style('width', '300px');   } |
