? jQuery CSS Manipulation in JavaScript

What is jQuery CSS?

• jQuery provides convenient methods to get and set CSS styles on elements.

• Simplifies cross-browser CSS manipulation compared to plain JavaScript.

Common jQuery CSS Methods

1. Get CSS Property

const color = $("#myDiv").css("color");console.log(color);  // e.g., "rgb(255, 0, 0)"

• Gets the computed style value of the first matched element.

2. Set Single CSS Property

$("#myDiv").css("color", "blue");

• Sets the CSS property for all matched elements.

3. Set Multiple CSS Properties

$("#myDiv").css({  "background-color": "yellow",  "font-size": "20px",  "border": "1px solid black"});

• Pass an object to set multiple styles at once.

4. Using CSS Classes (Recommended for complex styling)

$("#myDiv").addClass("highlight");$("#myDiv").removeClass("highlight");$("#myDiv").toggleClass("highlight");

• Adds, removes, or toggles CSS classes.

Example

<div id="myDiv">Hello World</div><script>  $("#myDiv").css("color", "red");  console.log($("#myDiv").css("color")); // Outputs the current color</script>

Note

• jQuery’s .css() accesses the computed style, not the inline style attribute.

• For performance and maintainability, prefer CSS classes over setting many inline styles dynamically.
