what makes up code?
• html is made up of elements or ‘tags’
• the content of tags are what you see on a page
• tags are the language you will be learning
What do tags look like?
<html> this is what an opening tag looks like
</html> this is what an closing tag looks like
how does code work?
• All web pages have three elements, opened and closed, that are needed to work properly
<html></html><head></head><body></body>
how they are organized<html>
</html>
<head></head>
<body>
</body>
<html> tells the browser the kind of doc
<head> helps search engines
<body> is where visual and functional items you see on a web page are put
understanding nesting
• nesting helps different elements in HTML appear correctly
• think of nesting like tupperware, you can fit different elements inside each other
• Those that can fit will work correctly
• Those that can’t, will not work right - not necessarily break but won’t work right
lets begin formatting text
<h1>hello world</h1><h2>hello world</h2><h3>hello world</h3><h4>hello world</h4><h5>hello world</h5><h6>hello world</h6><p>hello world</p>
What we do now
• Open up a text editing program on your machine
• MAC = Text Edit
• PC = TextEdit
• MAC == please turn off RTF and restart
• To the Web
