HTML and CSS Reference
In-Depth Information
he short answer is no. First of all, new versions of the HTML speciication
do not make older versions obsolete. For example, the irst home page I ever
created looks the same in Firefox and Chrome today as it did in Mosaic and
Arena in 1994. What's important is the assurance that the web pages we build
today will look and function the same in another 15 years. We may update
those pages for marketing and aesthetic reasons, but we will not be forced to
edit them for technical reasons. Second, if you already know some HTML, it
is not a matter of learning a new language or dialect, but simply incorporating
new elements into your HTML vocabulary.
If you are a content creator/editor using Web-based tools to update web
pages and post articles, you need to know that any HTML markup you use
in a blog post, press release, or email newsletter will be the same in all your
readers' browsers. It is best for you to stick with the elements and attributes of
HTML4 until HTML5 has been more widely adopted and more guidance is
forthcoming on how to use the new features.
If you design websites and keep up with tech trends on a regular basis, you
will learn from your online resources about browser support for new HTML5
elements, which you can incorporate into your work with appropriate fall-
backs and cross-browser testing. Now is the time to play with HTML5, while
you reexamine your Web design and development methods. he HTML5 Web
is collaborative.
If you manage a Web design company or development shop, your websites
are probably sophisticated enough that you already do browser detection. My
suggestion is to let one of your programmers become your HTML5 specialist,
creating HTML5-aware versions of some of your in-development and existing
websites.
Here are the important points to remember from this chapter:
HTML is a semantic markup language for online, hypertext-linked
documents.
.
he Web has a client/server architecture. Web servers respond to requests
from user agents such as web browsers, search robots, and web page
editors.
