Here & # 039; s What & # 039; Graceful Degradation & # 039; It is in ...

Definition:

Since web browsers the Web was made available, the customer their web pages in browsers that are very old and missing features of modern browsers can display. The progressive reduction is a strategy of manipulation of web design for different browsers.

A web design that was built to affect properly it is first seen by most modern browsers, and are then considered to be older, less affluent browser functions expected to deteriorate in a way that is but functionally is, however, with fewer features.

The main difference between the strategy of gradual deterioration and gradual improvement is where you start your design. If you start with the lowest common denominator, then add features of modern browsers to your web pages will use the progressive improvement. If you start with the most modern and avant-garde functions and back, with graceful degradation.

Graceful degradation means not tell your readers, "Download latest browser"

One of the reasons many modern designers do not like the approach of the progressive dismantling, because often is the requirement that the reader, please update your browser for the page to work. But these are not degraded. If you want to give yourself to write, "for this function used X-Download-browser", he left the area and moved the gradual deterioration in the design of the central browser.

A good rule of thumb is to have the same rules for graceful degradation follow, as if it were a gradual improvement:

1. Write HTML valid and standards compliant

1. Use external style sheets to your drawings and design
2. Use external scripts to connected interactivity
3. Make sure the content is accessible, even low-level browsers without CSS or JavaScript

Then go and build the most innovative design as you can! Ensure that degrades in less functional browsers, but it still works.
