Chapter 11, Problem 1FWD

Explanation of Solution

Consider the given web page link: “https://www.w3.org/TR/html-design-principles/”

Summary about the given web page and its reviews:

The given web page describes about the principles which is used in the HyperText Markup Language fifth revision (HTML5).

The principles cover the areas of compatibility, utility, and interoperability.

Compatibility:

There are many ways for compatibility; they are as follows:

• Supporting the existing content – This principle is used to support the language with existing content.
  • For example: Many webpages use the broken markup such as bad nested elements; so, we need to use the expected elements to provide the compatibility.
• Degrade gracefully – This principle applies to conforming language, that is, authors are frequently hesitant to use the new language that may cause problems in older user.
  • For example: The new element for multimedia is “<canvas>” or “<video>” to enable the fallback content.
• Do not reinvent the wheel – Do not implement the new technology for same purpose.
• Pave the Cowpaths – Use the existing technology instead of inventing new.
  • For example: always use the correct syntax or format while design the web page, use “<br/>” tag instead of “<br>”.
• Evolution not revolution – Sometimes, it is better to evolve an existing design instead of throwing it away; so, implement the existing code by adding new features.

Review of the principle:

As a web designer, designer should follow the below principles to attain the compatibility for a web page:

• The web designer should support the existing content or coding.
• They should not implement the new technology for same purpose.
• They can use existing technology instead of inventing new.
• Evolve an existing design instead of throwing it away.

Utility:

The following principles are used for designing purpose in effective manner:

• Solve real problems – Modifying the specifications should solve the real word problems whenever possible...
