Incorporate Attributes
Attribute: additional code within an opening element tag that specifies information about that element, e.g. <html lang="en"> To use an attribute, use Attribute name Attribute value surrounded by quotes Separated by an equal sign, e.g. <meta charset="utf-8">

lang attribute The lang attribute is used to identify the language of the content on a web page. The lang attribute is helpful to users of assistive technology such as screen readers that can adjust the pronunciation depending on the language used.
9
Charset attribute Specifies the character encoding for the HTML document. Common values are: UTF-8 - Character encoding for Unicode ISO Character encoding for the Latin alphabet Any character encoding can be used, but no browser understands all of them. The more widely a character encoding is used, the better the chance that a browser will understand it.
10
Implement the div ElemenT
Groups elements such as heading and its related paragraphs. Used as the parent element to the other nested elements. div element does not change the appearance of the web page.
11
SEMANTIC ELEMENTS GIVE MEANING
12
Add HTML5 Semantic Elements
All HTML elements have semantic value because they indicate the meaning of their content, e.g. h1 indicates a heading one p indicates a paragraph div element has limited semantic meaning because it groups elements but adds no other meaning
13
Several of the most common HTML5 semantic elements
Search engines use semantic elements to provide more accurate search results. Several of the most common HTML5 semantic elements
14
script element helps browsers interpret elements
Code with semantic elements and script
15
WHAT IS THE CORRECT ORDER?
<article> </article> <body> </body> <!DOCTYPE html> <footer>Contact us at </footer> <h2>Acme Company</h2> <head> </head> <header> </header> <html lang=“en”> </html> <nav>Links to other pages go here</nav> <p>This is a sample web page for Acme Inc. More will be added later.</p> <p>Second paragraph about Acme</p> <title>Acme Inc</title> <!DOCTYPE html> <html lang=“en”> <head> <title>Acme Inc</title> </head> <body> <header> <h2>Acme Company</h2> </header> <nav>Links to other pages go here</nav> <article> <p>This is a sample web page for Acme Inc. More will be added later.</p> <p>Second paragraph about Acme</p> </article> <footer>Contact us at </footer> </body> </html>

Use Special Characters
Some characters cannot be entered directly into HTML text They may be misinterpreted as computer instructions Character reference: formatted code that represents characters in the HTML character set Have the format &code;

Two types of character references
Numeric character reference, format &#code;, e.g. • for a bullet symbol Named character reference, only a few, format &code;, e.g. > for greater than symbol (>) Important character references
