## Description
|
|
<section id='description'>
|
|
You can also change the non-CSS properties of HTML elements with jQuery. For example, you can disable buttons.
|
|
When you disable a button, it will become grayed-out and can no longer be clicked.
|
|
jQuery has a function called <code>.prop()</code> that allows you to adjust the properties of elements.
|
|
Here's how you would disable all buttons:
|
|
<code>$("button").prop("disabled", true);</code>
|
|
Disable only the <code>target1</code> button.
