Realistic shadows using CSS3 without the use of images

Hello dear blog readers. We continue to develop the basis CSS3 , and now look at a few examples of how to create realistic shadows using CSS3 without the use of images . As we know the shadow is very widely used in the design, because it creates a shadow effect of realism. Previously used to create shadow images, but with the advent of CSS3 was possible to quickly and easily create realistic shadows.


What is the main advantage of the shadows created using CSS3, so it is in the simplicity of implementation. You just need to define the appropriate rules and assign them to the desired container. In an HTML document, you use only one tag, such as a tag <div>. Now you do not need additional markup, will be created as additional pseudo-elements and are placed behind the main object.
At the heart of rules for creating shadows are as follows:

CSS:

Source code:

.drop-shadow {
   position:relative;
   width:90%;
}

.drop-shadow:before,
.drop-shadow:after {
   content:"";
   position:absolute;
   z-index:-1;
}

Next, we must place the pseudo-elements and ask them to explicit or implicit dimensions:

CSS:

Source code:

.drop-shadow:before,
.drop-shadow:after {
   content:"";
   position:absolute;
   z-index:-1;
   bottom:15px;
   left:10px;
   width:50%;
   height:20%;
}

Then you can see examples of finished and complete the code required for realizayii.

When viewing the article is better to use the latest versions of browsers that support the specification CSS3. Otherwise, you can not see the realization of these examples to create realistic shadows using CSS3 without the use of images.
