Last time I wrote about two validation methods on the client site. I also admit that this kind of validation won’t protect your server from hacker attacks. This because HTML and JavaScript files could be changed by users. So in this post, I show you, how to build a validation function in PHP.
The websites are mostly constructed from three layer. First of all HTML wich creating a structure and content. Secondly, there is a CSS that includes how the website should look like.

The most popular HTML tag used on a webpage is an HTML form. It is used to get some data from visitors and display some results on the web page depends on how visitors fill data fields in this HTML form.

Have you ever have some problems with data transferring between HTML form and JavaScript? I had, and I had learn something new.

What exactly I needed to do in my task, and what new things about that I learned, you can find bellow.
A long, long, long time ago in there was no animation on the website. Just text, sometimes images, and hyperlinks. Then web developers used to animate elements on websites via JavaScript. That worked and still works, but today we can use CSS properties to make awesome animation on a webpage. In this post, I show you how to do that.
