Write a html program using all tags of html

It does not explain much of CSS. At the end of the tutorial, you will have made an HTML file that looks like this: Once you understand the principles, you may want to switch to more advanced tools, or even to commercial programs, such as Style Master, Dreamweaver or GoLive.

While this guide expects you to have some basic knowledge of computer systems and assumes you know a program language, it should also be an interesting read for people who are interested in emulation in general.

An emulator is a computer program that mimics the internal design and functionality of a computer system System A. It allows users to run software designed for this specific system Sytem A on a totally different computer system or architecture System B. Often people confuse a simulator with an emulator and vice versa.

Pong is a 2D tennis game which was developed by Atari and ran on their own hardware. Basically what happened is that people created their own implementation clones of the game Pong. In this case they simulated the looks and game behavior of Pong. In case of an emulator, we choose not to re-implement the game Pong for our native system.

Instead, we re-create the environment with a computer program which allows us to run the original machine code of Pong. What is a CHIP-8? Games written in the Chip 8 language could easily run on systems that had a Chip 8 interpreter.

Why start with a CHIP-8 emulator? Writing a Chip 8 emulator is probably the easiest emulation project you can undertake. Due to small number of opcodes 35 in total for Chip 8 and the fact that a lot of instructions are used in more advanced CPU s, a project like this is educational get a better understanding of how the CPU works and how machine code is executedmanageable small number of opcodes to implement and not too time consuming project can be finished in a few days.

CPU Specifications When you start writing an emulator, it is important that you find as much information as possible about the system you want to emulate.

Try to find out how much memory and registers are used in the system, what architecture it is using and see if you can get hold of technical documents that describe the instruction set. In the case of the Chip 8, I would recommend taking a look at the Chip 8 description on Wikipedia.

The Chip 8 has 35 opcodes which are all two bytes long.

To store the current opcode, we need a data type that allows us to store two bytes. An unsigned short has the length of two bytes and therefor fits our needs: Eight bits is one byte so we can use an unsigned char for this purpose: The chip 8 has one instruction that draws sprite to the screen.

Drawing is done in XOR mode and if a pixel is turned off as a result of drawing, the VF register is set. This is used for collision detection. The graphics of the Chip 8 are black and white and the screen has a total of pixels 64 x This can easily be implemented using an array that hold the pixel state 1 or 0: The Chip 8 has none, but there are two timer registers that count at 60 Hz.

When set above zero they will count down to zero. It is important to know that the Chip 8 instruction set has opcodes that allow the program to jump to a certain address or call a subroutine. The stack is used to remember the current location before a jump is performed. So anytime you perform a jump or call a subroutine, store the program counter in the stack before proceeding.

The system has 16 levels of stack and in order to remember which level of the stack is used, you need to implement a stack pointer sp. It does not teach you how to use GLUT or SDL to handle graphics and input but merely shows you how the flow of your emulator should be. In this example we assume you will create a separate class to handle the opcodes.

Setup the graphics window size, display mode, etc and input system bind callbacks Line Clear the memory, registers and screen Line Copy the program into the memory Line Emulate one cycle of the system Line Because the system does not draw every cycle, we should set a draw flag when we need to update our screen.HTML Tutorial - Learn to Design a Website using HTML by Christopher Heng, leslutinsduphoenix.com If you happen to use a particular text editor to write HTML code, you will end up calling it an HTML editor.

Instead, you format a page in HTML by adding different HTML tags, or by using CSS. Write HTML Using Notepad or TextEdit. Web pages can be created and modified by using professional HTML editors. However, for learning HTML we recommend a simple text editor like Notepad (PC) or TextEdit (Mac).

We believe using a simple text editor is a good way to learn HTML.

When editing HTML it's easy to make mistakes. Wouldn't it be nice if there was a simple way to fix these mistakes automatically and tidy up sloppy editing into nicely layed out markup?

Well now there is! Dave Raggett's HTML TIDY is a free utility for doing just that. It also works great on the.

In order to get the data in the correct spot, you need to add another set of tags around each piece of data using the td element.. Table Data Cell. The td element defines the . Gnulib. GNU software has a well-deserved reputation for running on many different types of systems.

While our primary goal is to write software for the GNU system, many users and developers have been introduced to us through the systems that they were already using.
