How Can I Efficiently Define Multiple CSS Attributes in jQuery?

Multiple CSS Attribute Definition in jQuery

While the ability to define multiple CSS attributes in a single line is supported in jQuery, it can lead to readability issues. The jQuery API provides two alternative approaches.

DOM Notation

jQuery understands both the DOM and CSS notations for property names. In DOM notation, hyphenated properties (e.g., "background-color") can be written without quotes:

.css({backgroundColor: "#ffe", borderLeft: "5px solid #ccc"})

Object Literal

To define multiple CSS attributes, use an object literal as an argument to the .css() method:

.css({
   'font-size' : '10px',
   'width' : '30px',
   'height' : '10px'
});

Recommendations

It's recommended to use .addClass() and .removeClass() methods for style management, even with a single attribute. This ensures maintainability and readability. However, if the need arises for multiple CSS property assignments, the object literal approach is preferable to stringing out properties in multiple .css() calls.

Note:

Remember to enclose any property names containing a hyphen in quotes when using CSS notation.
