This method sets CSS properties to the specified elements directly overriding the styles defined in the style sheet (if any). It allows us to have better control of application of styles on the individual elements as well as a collection of elements: .css(property, value) Here property is the CSS property name that we want to set and value can be either the property value that we want to assign to the property or it can be a function that returns the property value to set. Here's an example: $('p').css('color':'blue'); It sets the color of the paragraph text to blue. The following uses a function that returns the height of the img element after incrementing it by 30; that is, it will increase the height of the img element by 30px: $('img').css('height',function(){ return $(this).height()+30;}); The output of our solution will display the button and the paragraph text as shown in Figure 3-9.

The button and the paragraph text We can see in the jQuery code that css() defines several properties, like the background-color property to apply cyan as the background of the paragraph text, font-weight to make the text appear in bold, and color to change the foreground color of the paragraph text to blue. The properties in the css() method will be applied to the paragraph text when the mouse is moved over the button and may appear as shown in Figure 3-10 (despite this being in black and white, you can see the general idea).

3-8. Making an Image Bright and Blurred with Mouse Movements
Problem
Imagine you have an image displayed on your web page along with a button. The image is initially blurred.You want to make it so that when the mouse is moved over the button, the image becomes bright and when the mouse is moved away from the button, the image again becomes blurred. Also, you want to increase the height and width of the image when you click on the button. Solution
In this recipe we will be making use of the different mouse event-handling methods you saw in Recipe 34. So, if you don t know the workings of the different mouse event methods, like mouseover(), mouseout(), mousedown(), etc., go through Recipe 3-4 before you attempt to work through this recipe. CHAPTER 3 EVENT HANDLING
Let s assume an HTML file that displays a button and an image, as shown here: <body> <span class="buttons">Bright Image</span> <img src="cell.jpg"/> </body> The text Bright Image is enclosed within a span element of the class buttons so that the style rule buttons defined in the external style sheet is applied to the text to give it the shape of a button. .buttons{ width: 100px; float: left; text-align: center; margin: 5px; border: 2px solid; font-weight: bold; } The jQuery code to apply effects to the image is as follows: $(document).ready(function() { $('img').css('opacity',0.4); $('.buttons').bind('mouseover', function(){ $('img').css('opacity',1.0); }); $('.buttons').bind('mouseout', function(){ $('img').css('opacity',0.4); }); $('.buttons').bind('mousedown', function(){ $('img').css('width',function(){ return $(this).width()+50;}); $('img').css('height',function(){ return $(this).height()+30;}); }); });
