Word-Wrap: Force Text to Wrap

CSS: Word-Wrap Property (view demo)

You can specify either normal or break-word value with the word-wrap property. Normal means the text will extend the boundaries of the box. Break-word means the text will wrap to next line.

.break-word {
  word-wrap: break-word;
}

The Basics of CSS3

RGBA

The first three values are RGB color values and the last value is the level of the transparency (0 = transparent and 1 = opaque).

RBGA can be applied to any properties associated with color such as font color, border color, background color, shadow color, etc.

Text Shadow

Text shadow is structured in the following order: x-offset, y-offset, blur, and color;

Set a negative value for x-offset to shift the shadow to the left. Set a negative value for y-offset to shift the shadow to the top. Don't forget you can use RGBA values for the shadow color.

You can also specify a list of text-shadow (separated by a comma). The following example uses two text-shadow declarations to make a letter press effect (1px top and 1px bottom).
text-shadow: 0 1px 0 #fff, 0 -1px 0 #000;

Border Radius

The shorthand for border radius is similar to the padding and margin property (eg. border-radius: 20px). In order for the browsers to render the border radius, add "-webkit-" in font of the property name for webkit browsers and "-moz-" for Firefox.

You can specify each corner with a different value. Note Firefox and Webkit has different property names for the corners.

Box Shadow

The structure for box shadow is same as the text-shadow property: x-offset, y-offset, blur, and color.

Again, you can apply more than one box shadow. The following example is a list of three box shadow declarations.
-moz-box-shadow:
-2px -2px 0 #fff,
2px 2px 0 #bb9595,
2px 4px 15px rgba(0, 0, 0, .3);

CSS3 Dropdown Menu

Preview

The image below shows how the menu will look if CSS3 is not supported.

One Gradient Image is Used

A white-transparent image is used to achieve the gradient effect. Because the new CSS3 gradient feature is not supported by all browsers yet, it is safer to use a gradient background image.

The instensitiy of the gradient can be changed by shifting the background image up or down. Also, the gradient color can be easily adjusted by changing the background color.

CSS Code

I'm not going to explain the CSS line by line. The images below explain the key points on how this dropdown is coded.

Update Apr 13 2010: Pure CSS Dropdown (No Image Used)

The following demo used CSS gradient and IE gradient filter instead of the gradient image. It works for Webkit browsers, Firefox 3.6+, and IE.

MooTools Image MouseOvers

Creating mouseover code can be a real mess but using MooTools I put together a solution that saves me time and keeps my code super clean. There are some practices that I use with my theory. All "mouseover" versions of the image end in "-mo". For example, sugar.jpg is the standard image while sugar-mo.jpg is the mouseover version. Also, I use a CSS class mo to identify which items have mouseovers. I also stick to one file extension and assume that the mouseover image's file extension is the same as the original file's extension.

Code:

                     window.addEvent('domready', function() {

$$('img.mo').each(function(img) {
  var src = img.getProperty('src');
  var extension = src.substring(src.lastIndexOf('.'),src.length)
  img.addEvent('mouseenter', function() { img.setProperty('src',src.replace(extension,'-mo' + extension)); });
  img.addEvent('mouseleave', function() { img.setProperty('src',src); });
}); 

});

The Usage:

<a href="/"><img src="/graphics/sugar.jpg" alt="Sugar" class="mo" height="50" width="150" /></a>

That's it. Simply add the mo CSS class to the image and save yourself any ugly, bloated "onmouseover" code. Remember not to use the mo CSS class anywhere else!
