WEB PAGE LAYERS CODE

CSSĬSS (cascading style sheets) is used to add some “pizazz” to your web pages. We’ll be diving into examples of HTML “code” later, so stay tuned. This is also what makes it fairly easy to learn. HTML is not a programming language, as it doesn’t define variables, data types, control structure or the like. Thankfully HTML isn’t too tough to learn as it’s more of a game of memorizing the most popular tags and using them to create your simple web pages. These tags are used to define things like the title of the webpage (which appears in the tab of your browser), the actual text that appears on the page, images, buttons and more. HTML defines a bunch of different HTML elements known as tags that are put together to make up the basic layout of a web page. All browsers follow the rules laid out in HTML (currently in its 5th iteration). HTML (HyperText Markup Language) is a technology used to communicate with web browsers. Let’s dive into the overviews of each of these big players, shall we? HTML

The four big players (in terms of technology) in the presentation layer are as follows: Having said that, we'll be focusing on the presentation layer.

If you separated your code out properly, switching databases shouldn't be too big of an issue. Same rules apply to the business and data layers. So if you keep all of your presentation layer code in one area of your application, switching presentation layer technologies shouldn't be too difficult. It's a design pattern used to help separate your code out in three distinct areas that (if need be) can easily be switched out with another programming language or technology. Now, these three layers are typically related to enterprise web applications. The presentation layer is one of the three main layers in object-oriented programming.
