This is our Second Principle of clean HTML code: Use nested tags when possible. Be aware that WYSIWYG editors will frequently update formatting by adding layer after layer of nested code. So while you are cleaning up code look for redundant nested code placed there by your WYSIWYG editing program.

A big problem with using HTML tags is that we need to repeat tag coding whenever we change formatting. The advent of CSS allows us a great advantage in clean coding by allowing us to layout formatting once in a document, then simply refer to it over and over again.

If we had six paragraphs in a page that switch between two different types of formatting, such as headings in Blue, Bold, Ariel, size 4 and paragraph text in Black, Times, size 2, using tags we would need to list that complete formatting each time we make a change.

(font face=”Ariel” color=”blue” size=”4”)(b)Our heading(/b)(/font) (font face=”Times color=”black” size=”2”)Our paragraph(/font) (font face=”Ariel” color=”blue” size=”4”)(b)Our next heading(/b)(/font) (font face=”Times color=”black” size=”2”)Our next paragraph(/font)

We would then repeat this for each heading and paragraph, lots of html code.

With CSS we could create CSS Styles for each formatting type, list Styles once in Header of page, and then simply refer to Style each time we make a change.

(head) (style type="text/css") (!-- .style1 { font-family: Arial, Helvetica, sans-serif; font-weight: bold; font-size: 24px; } .style2 { font-family: "Times New Roman", Times, serif; font-size: 12px; } --) (/style) (/head) (body) (p class="style1")Heading(/p) (p class="style2")Paragraph Text(/p) (/body)

Notice that Styles are created in Head section of page and then simply referenced in Body section. As we add more formatting we would simply continue to refer to previously created Styles.

This is our Third Principle of Clean HTML Code: Use CSS styles when ever possible. CSS has several other benefits, such as being able to place CSS styles in an external file, thereby reducing page size even more, and ability to quickly update formatting site-wide by simply updating external CSS Style file.

So with some simple cleaning of your HTML code you can easily reduce file size and make a fast loading, lean and mean web page.

As for SIP VoIP in home, there is too little incentive for savvy consumers to part with more of their hard earned communications dollars for an industry offering that simply does not meet needs of user. Until something concrete can be done to move SIP VoIP forward, service based on P2P such as Skype seems to be only sensible choice on kitchen table. Why should home users pay $15 or more per month for less reliable communications than they already have with their land line? Skype gives users ability to experience “best effort” voice over Internet for FREE. Could this be reason why more than 125 million copies of Skype’s P2P software has been downloaded? And for occasions where interconnection with existing circuit-switched telephone networks is required, Skype offers a very competitive 2 cents per minute interconnection rate. With Skype you can talk for 12 ½ hours interconnected to phone system for same cost as a basic rate SIP VoIP service.

Until genuine changes are made to support SIP VoIP QoS there does not appear to be a convincing or compelling reason today for users to choose anything other than P2P VoIP services such as Skype to render Internet “best effort” home phone services.
