Different JavaScript codes to get marked checkboxes value <script> document.getElementById('btn').onclick = function() { var markedCheckbox = document.getElementsByName('pl'); for (var checkbox of markedCheckbox) { if (checkbox.checked) document.body.append(checkbox.value + ' '); } }

The <input type="checkbox"> defines a checkbox. The checkbox is shown as a square box that is ticked (checked) when activated. Checkboxes are used to let a user select one or more options of a limited number of choices. Tip: Always add the <label> tag for best accessibility practices!

Navigate to the page you would like to change all checkbox sizes on and add the following code to the CSS tab of the page. input[type=checkbox] { margin: 4px 0 0; line-height: normal; width: 20px; height: 20px; }

Since clicking the label essentially clicks the checkbox, I would add padding or width to the label surrounding the checkbox so that it extends as far as you need your clickable area to be.

Method 1: The checkbox size can be set by using height and width property. The height property sets the height of checkbox and width property sets the width of the checkbox. Output: Note: This works well for Google Chrome, Microsoft Edge and Internet Explorer.
