Now, we will understand HTML5 with a smart concise cheat sheet, plus, you can try the html5 code/script online without downloading any software via online real-time code editor here!
Let's start learning..
HTML5 Standard Structure
<html></html> these tags are used at the beginning and end of an HTML document. This is known as the root element. Using these tags tells the website that the web page is being written in HTML5, and that all the other tags within these are HTML formatted.<title></title> This is used for the title tag of the page. Here you'll place a title that is useful to both search engines and users.
Here's what a typical layout looks like:
<html><meta/> includes additional information about the page. This includes descriptions, author, publish date, keywords, and other off-page information.
<head>
<title>HTML5 Cheat Sheet</title>
</head>
<body>

</body>
</html>
<style>..</style> used to include document style information which is usually CSS.
<head></head> use these to group information specific to the page. This includes title tags, meta descriptions, and links to both script and style sheets.
<body></body> between these tags is where you'll place all the content for users. This includes text, images, and graphic elements.
<base /> signifies the Base URL and specifies all relative links in the document.
<link /> creates association with external page like style sheets.
<script>..</script> all the information of links to external scripts.
