  • Explain Html and demonstrate a html page

    • What does HTML stand for? Ask class Answer: Hypertext Markup Language: Mark up language so way of describing text and how it should look.

    • Explain may ways of creating a website: e.g. can use wix or wordpress which are more drag and drop. But all create HTML, js, and css. And this is what brower reads and unpacks to display info.

    • Explain at moment html file browser just unpacking a file like word unpacks a word document. And that file is local. Later file will be online and browser will go to a site to get file (as in diagram)

    • Explain tag is <...>

    • Go through some key tags: Like:

      <html>, <body>, <head>, <p>, <h1>, <title>, <div>

<ul>, <ol>, <li>

      • Title: shows up on the tab header of the page

      • Div: grouping element. Will cover in more depth later in the course but this is one of the most versatile element in html

      • List element. Explain difference between <ul> and <ol>.

<head>
<title>This is a title</title>
</head>
<body>
<div>

</body>
</html>
