Is the doctype declaration necessary only for rendering webpages in standard mode with IE6, or does it serve a broader purpose?
Is the doctype declaration necessary only for rendering webpages in standard mode with IE6, or does it serve a broader purpose?
The document type declaration informs all web browsers about the type of content present on the page. While many browsers may display similar results, Internet Explorer has two distinct rendering modes, leading to noticeable differences in display.
It is recommended to include a doctype declaration in every HTML document. In the future, it will be even simpler with the HTML 5 standard:
<!DOCTYPE html>
Contrastingly, HTML 4 looks like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
With options for Transitional or Strict specifications.
All web browsers use this code to understand how to display the webpage, not just IE6.

Using the Doctype declaration can help ensure that your webpage aligns with the W3C standards.
