Question:
What is the purpose of the <!DOCTYPE ..> tag in HTML pages and what should I put in there?Answer:
The <!DOCTYPE ..> tag is a special declaration in the very first line of your webpage, it comes even before the <HTML> tag. This tag informs a validator tool what rules to use when it has to validate your page. Newer browsers (IE 6+, Mozilla, NS6+, Opera, IE 5+ on Mac) use this setting to determine whether to display your page in 'Quirks' or 'Standards' mode.Visit this web site to try an online validator:

// HTML 4.01 transitional doctype supports all attributes of HTML 4.01, // presentational attributes, deprecated elements, and link targets. // It is meant to be used for webpages that are transitioning to HTML 4.01 strict: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> // HTML 4.01 Strict is a trimmed down version of HTML 4.01 with emphasis on // structure over presentation. Deprecated elements and attributes // (including most presentational attributes), frames, and link // targets are not allowed. CSS should be used to style all elements: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> // HTML 4.01 frameset is identical to Transitional above, // except for the use of <frameset> over <body>: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd"> | ||
