Hello Coders!

In this article I will list a few advises on how to optimize your PHP web application performance. All these tips below I learned myself or from co-workers, blog articles and books. Keep in mind though that usually there is no need to go nuts when it comes to performance optimization. So, please don't open your IDE right away and don't try to use all tips together. Simply get an idea and note something that could be useful in your specific case.

Basic approach and main idea

Very often, web designers use CSS rounded corners to make websites nicer. This blog uses rounded corners too. You could use different methods to create rounded corners on your web site, but from my point of view the simplest one of these methods is the method that uses CSS3.

Unfortunately, this method won't work in IE (what a surprise!), but, fortunately, there is a hack exists that can fix this problem.

For most of web browsers the following code will work:

<style>
#container {
  width: 200px;
  height: 200px;
  background-color: #cccccc;	
}
.rounded {
  -moz-border-radius: 10px; /* Works in Firefox */
  -webkit-border-radius: 10px; /* Works in Safari, Chrome */
  border-radius: 10px; /* It's CSS3 */
}
</style>

<div id="container" class="rounded"></div>
