The CSS properties applied to the image makes use of the float property to make the image float to the left in the browser window (allowing the text to appear on its right); the width property is used to confine the image to the size of 200px (any size less than the browser window s total width), so there's space for the text to wrap around the image. The height property is used to limit the image height to a particular size. When right is assigned to the clear property, it will make the extra paragraph text move to the left. That is, it tries to make the space on the right side clear but fill the space on the left. Hence, the extra text of the paragraph that extends beyond the image height moves to the left side, wrapping text around the image. When we apply the preceding CSS properties to the image and paragraph elements, we get the output shown in Figure 10-31.

In order to create a drop shadow, we need to make two images: one to server as a drop shadow on the right side of the image, and the other to create a shadow effect at the bottom of the image. Let us name the drop shadow on the right of the image shadowright.jpg , as shown in Figure 10-32.

CHAPTER 10 USING CSS
Similarly, the drop shadow at the bottom of the image is named shadowbottom.jpg and appears as shown in Figure 10-33.
Figure 10-33. The background shadow image for the bottom Assuming that an image file called image4.jpg exists, the HTML code to display the image is as shown here: <body> <span class="shadow"><img src="image4.jpg" /></span> </body> The style rules to be applied to the img element and the span element are applied via the css() method, as shown in the following jQuery code: $(document).ready(function() { $('span').css({'background':'url(shadowright.jpg)', 'background-repeat':'norepeat','background-position':'bottom right', 'padding':'0 10px 0 0'}); $('img').css({'width':'200px','height':'200px','background':'url(shadowbottom.jpg)', 'background-repeat':'no-repeat','background-position':'bottom', 'padding':'0 0 10px 0' }); });
How It Works
In the preceding HTML file, the img element is enclosed within a span element because we need to apply two style rules to the img element: one for the drop shadow on the right side of the image and the other for the drop shadow at the bottom of the image. But we cannot apply more than one style rule to an element. So, to apply two style rules to the img element, we ll enclose it with a span element so that one style rule can be applied to the span element (which will eventually be applied to the img element), and the other style rule can be applied to the img element itself. The first css() call contains four properties: The background:url property is set to display the image stored in the file shadowright.jpg at the background of the image. The background-repeat property is set to no-repeat to display the shadow image only once. The background-position property is set to bottom right to display the shadow image at right side of the image, aligned with the bottom. The padding property is used to set the distance of the shadow image from the actual image. This helps in deciding the width of the shadow.
Similarly, the second css() call contains six properties:
CHAPTER 10 USING CSS
The width and height properties are set to 200px to constrain the width and height of the actual image being displayed to 200 pixels. The background:url property is set to display the image stored in the file shadowbottom.jpg in the background of the image. The background-repeat property is set to no-repeat to display the shadow image only once. The background-position property is set to bottom to display the shadow image at the bottom of the actual image. The padding property is used to set the distance of the shadow image from the actual image.
On application of the preceding properties to the image in the HTML file, the image will appear with the drop shadows on the right and bottom, as in Figure 10-34.
