								## Description
  
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								< section  id = 'description' >  
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								We can also change the CSS of an HTML element directly with jQuery.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								jQuery has a function called < code > .css()< / code >  that allows you to change the CSS of an element.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								Here's how we would change its color to blue:
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								< code > $("#target1 ").css("color", "blue");</ code >  
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								This is slightly different from a normal CSS declaration, because the CSS property and its value are in quotes, and separated with a comma instead of a colon.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								Delete your jQuery selectors, leaving an empty < code > document ready function< / code > .
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								Select < code > target1< / code >  and change its color to red.
							 
						 
					
						
							
								
							 
							
								
							 
							
								 
							
							
								< / section >
