Summary

Writing computer code should be performed with a text editor to produce a plain text file.

Code should first be checked for correct syntax (spelling and grammar).

Code that has correct syntax can then be run to determine whether it performs as intended.

Code should be written for human consumption as well as for correctness.

Comments should be included in code and the code should be arranged neatly so that the structure of the code is obvious to human eyes.

HTML is a simple language for describing the structure of the content of web pages. It is a useful cross-platform format for producing reports.

CSS is a language for controlling the appearance of the content of web pages.

The separation of code for a web page into HTML and CSS helps to avoid duplication of code (an example of the DRY principle in action).

HTML and CSS code can be run in any web browser.
