How Can I Modify CSS Properties Using jQuery's `css()` Method?

How to Change CSS Properties Using jQuery

In jQuery, you can modify CSS properties of HTML elements using the css() method. To target specific elements, you use selectors such as $("h1") or $("#myParagraph").

To demonstrate, here's an example:

$(function() {
  $("h1").css("backgroundColor", "yellow");
  $("#myParagraph").css({"backgroundColor": "black", "color": "white"});
  $(".bordered").css("border", "1px solid black");
});

However, sometimes CSS changes may fail. To troubleshoot, ensure that:

• The jQuery library is included: Verify that jQuery.min.js is correctly referenced in your element.
• Selector is correct: Check if the selector matches the element you intend to style.
• Property name and value are valid: Refer to the correct CSS property, e.g., "backgroundColor" instead of "background-color".
• Closing curly braces: All CSS properties within the object literal, as seen in $("#myParagraph").css(...), should be followed by a comma and enclosed in curly braces.

In the provided example, the missing closing curly brace for the $("#myParagraph").css(...) line likely caused the issue. To fix it, ensure it reads:

$("#myParagraph").css({"backgroundColor": "black", "color": "white"});

For further clarification, consult the official jQuery API documentation for the css() method.
