							|  |  |  | ## 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. |
