There are 4 basic elements used by almost every web page. These are :
<html>
This tells the browser that this is an HTML (Hyper Text Markup Language) document.
<head> This is where you put your keywords and description for the search engines. The browsers and search engine spiders can read this section, but it doesn't show up on the page itself.
<title> The title for your page (what you see at the upper left of the browser window).
<body> This is where you put your page content that you want the rest of the world to see.
Whenever you use an element in a web page, get into the habit of "closing" that element. This is simply a matter of typing the element again, but adding a forward slash (/). Though there are a few elements that do not require closing, it doesn't hurt if you close them anyway, and you'll save yourself a lot of headaches later if you have a problem with your web page not displaying properly.
So, if I were going to start a new web page, it would start out looking like this :
<html>
<head>
<title>PUT YOUR PAGE TITLE HERE</title>
<meta name="description" content="PUT YOUR PAGE DESCRIPTION HERE">
<meta name="keywords" content="PUT YOUR PAGE KEYWORDS HERE">
</head>
<body>
YOUR PAGE CONTENT WOULD GO HERE
</body>
</html>
