HTML and CSS Reference
This tag informs the web browser to render the page in standards mode. According to
the HTML5 spec from W3C, this is required for HTML5 documents. This tag simplifies
a long history of oddities when it came to rendering HTML in different browsers. This
should always be the first line of HTML in a document.
This is the <html> tag with the language referenced: for example, “en” = English. Some
of the more common language values are:
Chinese - lang = “zh”
French - lang = “fr”
German - lang = “de”
Italian - lang = “it”
Japanese - lang = “ja”
Korean - lang = “ko”
Polish - lang = “pl”
Russian - lang = “ru”
Spanish (Castilian) - lang = “es”
This tag tells the web browser which character-encoding method to use for the page.
Unless you know what you're doing, there is no need to change it. This is a required
element for HTML5 pages.
This is the title that will be displayed in the browser window for the HTML page. This
is a very important tag, as it is one of the main pieces of information a search engine
uses to catalog the content on the HTML page.
A Simple HTML5 Page
Now let's look at this page in a web browser (this would be a great time to get your
tools together to start developing code). Open your chosen text editor, and get ready
to use your preferred web browser: Safari, Firefox, Opera, Chrome, or IE.
1. In your text editor, type in the code from Example 1-1 .
2. Save the code as CH1EX1.html in a directory of your choosing.
