"Statistics are important information. From the statistics below, you can see that Firefox and Internet Explorer are the two most popular browsers."
"The market share of web browsers can be estimated based on the user-agent strings of visitors to popular websites. Statistics from safalra.com suggest a market share last month of 40% for Internet Explorer based browsers, and 52% for Gecko based browsers (such as Mozilla Firefox). "

"These are the HTML Meta Tags that I find useful or interesting. I am not intending to document all possible Meta Tags here. Check the references for more detail and other Meta Tags."
"You’ve done all the right stuff, but your site doesn’t look or work as it should in the latest browsers.
You’ve written valid XHTML and CSS. You’ve used the W3C standard Document Object Model (DOM) to manipulate dynamic page elements. Yet, in browsers designed to support these very standards, your site is failing. A faulty DOCTYPE is likely to blame.
This little article will provide you with DOCTYPEs that work, and explain the practical, real–world effect of these seemingly abstract tags."
"Quirks mode and strict mode are the two ’modes’ modern browsers can use to interpret your CSS. This page gives a short overview of the reasons for and the differences between these two modes."
"DOCTYPE And Browser Modes
HTML: DOCTYPE a režimy prohlížečů
Modern browsers use the "doctype sniffing" to distinguish older and newer versions of the (X)HTML languages. The proper formatting mode is selected according to the specified document type. The page is then formatted either in an obsolete, but more compatible way (non-standard, quirk mode) — or using modern standards (standard mode)."

"This section describes the HTML syntax in detail. In places, it also notes differences between the the HTML syntax and the XML syntax, but it does not describe the XML syntax in detail (the XML syntax is instead defined by rules in the [XML] specification and in the [Namespaces in XML] specification)."
"4.6. Empty Elements
Empty elements must either have an end tag or the start tag must end with />. For instance, <br/> or <hr></hr>. See HTML Compatibility Guidelines for information on ways to ensure this is backward compatible with HTML 4 user agents."
"Let's also pretend, for the sake of argument, that you're validating your spiffy new XHTML markup on a regular basis. You might even have one of those sporty "valid XHTML" badges lurking at the bottom of pages. Good for you."
