This is our class project, but you can make anything you want out of it. Providing you with tools and resources to make what you want of it.
Today we will be learning how to code a site from scratch using paragraphs, headings, links, images, and lists.
Today: HTML 'playground' to get acclimated (the ugly sketching phase of web development!); Next week: CSS for styles.

<!-- Fundamental Structure of an HTML File -->
<section>
<h3>The Fundamental Structure of an HTML File</h3>
<p class="blue">Doctype</p>
<p>The first thing in an HTML file is the doctype, which tells the browser which language the page is using:</p>
<pre class="apache nowrap">
<code>
<!DOCTYPE html>
</code>
</pre>
<img src="img/document-types.jpg" alt="Various document types" />
<p><small>The doctype is case-insensitive. <br/>DOCtype, doctype, DocType and DoCtYpe are all valid.</small></p>
<aside class="notes">
Exclamation mark indicates informative content that doesn't show up as text on the screen. Example: A human can look at a type of document and understand what type of document that is (letter, award, outline, etc.), but a browser has to be told specifically what it's looking at. Reads from top to bottom -- now that it knows it's HTML, it moves on to parsing the rest of the document as HTML.

<h3>The Fundamental Structure of an HTML File</h3>

<li>The page's <span class="orange">title</span></li>
<li><span class="orange">Meta information</span> about the page: Meta information is not visible to the user, but has many purposes, one of which is to tell search engines about your page, who created it, and the page's description</li>

<ol>
<li>Whenever you add a 'child' element:
<pre><code class="html"><ul>
</ul></code></pre> <p> </p>
</li>
<li>... indent it on a new line!
<pre><code class="html"><ul>
<li>I'm indented!</li>
<li>I'm also indented!</li>
</ul></code></pre>

<aside class="notes">Helps you more obviously see the family relationships and troubleshoot problems.</aside>
</section>
<section>
<h3>HTML Coding Tip #3</h3>
<p>HTML ignores multiple whitespaces in a row. You can add consecutive white space characters (spaces, tabs, & carriage returns) into your HTML, but when you view that page — <em>all but one disappears!</em></p>
<p> </p>
<div>
<div class = "left" style = "width:50%">
<p><span class="orange"><u>HTML:</u></span></p>
<pre class="html"><code>
<p>Two carriage returns
Three carriage returns
Plus multiple spaces ...</p>
</code></pre>
</div>
<p><span class="orange"><u>Result:</u></span></p>
<div>
<p style="font-size:90%;">Two carriage returns
Three carriage returns
Plus multiple spaces ...</p>
</div>
<div class ="clear"></div>
</div>
<p></p>
<p><small>To force consecutive spaces to show, use <em>&nbsp;</em> (stands for <em>"no-break space"</em>) in your HTML instead of spaces.</small></p>

This is very different from a word processor. You can use that to your advantage, for organizational purposes.
