.css
Description: Set one or more CSS properties for the set of matched elements. As with the .prop() method, the .css() method makes setting properties of elements quick and easy. This method can take either a property name and value as separate parameters, or a single object of key-value pairs. When a number is passed as the value, jQuery will convert it to a string and add px to the end of that string. If the property requires units other than px, convert the value to a string and add the appropriate units before calling the method. When using .css() as a setter, jQuery modifies the element's style property. As of jQuery 1.8, the .css() setter will automatically take care of prefixing the property name. As of jQuery 1.6, .css() accepts relative values similar to .animate(). As of jQuery 1.4, .css() allows us to pass a function as the property value: This example sets the widths of the matched elements to incrementally larger values. Change the color of any paragraph to red on mouseover event. Related:  practice animate tricks

.animate Description: Perform a custom animation of a set of CSS properties. The .animate() method allows us to create animation effects on any numeric CSS property. The only required parameter is a plain object of CSS properties. This object is similar to the one that can be sent to the .css() method, except that the range of properties is more restrictive. Animation Properties and Values All animated properties should be animated to a single numeric value, except as noted below; most properties that are non-numeric cannot be animated using basic jQuery functionality (For example, width, height, or left can be animated but background-color cannot be, unless the jQuery.Color plugin is used). In addition to style properties, some non-style properties such as scrollTop and scrollLeft, as well as custom properties, can be animated. Shorthand CSS properties (e.g. font, background, border) are not fully supported. Animated properties can also be relative. Duration Callback Functions Basic Usage Easing Demo:

jQuery css() Method Things you may not know about jQuery I was going to do a bit of a series, releasing a jQuery tip every day or week or something, but I think I’m a little too lazy to commit to something like that. So I’ve compiled them all into one post! I’ll probably add to the list at later dates so make sure to bookmark it! Do you have a tip nobody knows about? .hover Bind one or two handlers to the matched elements, to be executed when the mouse pointer enters and leaves the elements. .hover( handlerIn, handlerOut )Returns: jQuery Description: Bind two handlers to the matched elements, to be executed when the mouse pointer enters and leaves the elements. version added: 1.0.hover( handlerIn, handlerOut )handlerIn A function to execute when the mouse pointer enters the element.handlerOut A function to execute when the mouse pointer leaves the element.

Randomize CSS Properties using jQuery or JavaScript There are times when you’re working on a web development project when you want to randomize a CSS property. The simple act of randomizing a property can give a site a more interactive feel, as long as it’s used subtly. If you start randomizing everything on your site then it’ll lose it’s feel and identity to the user. The last thing you want is your site to feel like a completely different website every time someone visits it. That being said, one popular use of randomizing CSS properties is to randomize a background, whether that’s just a random color being chosen or a random image. The snippets in this article were originally created for that very purpose, randomizing a background. CSS Random Background Color The first example will look at selecting a random background, with one example using vanilla JavaScript and another using jQuery.

It’s a Rainbow! – Color Changing Text and Backgrounds w/ jQuery Here’s a quick and easy way to cycle between multiple colors smoothly. Normally you would define the (background) color in the CSS and that would be the end of it.
