## 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.
