first HTML document</TITLE> </HEAD> <BODY> <P>Hello world! </BODY> </HTML>
html 3.2 1997-01-14
html 2? html 1? There are suddenly no links for
these specs. http://memtech.website/~bkmontgomery/
html == html5.1 <!doctype html>
<!doctype html> <html> <head> <title>Example</title> <base href=“http://example.com/"> <meta charset="utf-8"> <meta
name="description" content="Actual description"> </head> <body> </body> </html>
the rules ok, just my rules
None
Mind your <head> Use unique content for your <title> Write
a decent <meta name=“description” …> Declare a <base> tag.
headings Headings (<h1> - <h6>) imply an hierarchy. They have
meaning (semantics). Don’t use them for “text size”. Don’t skip sizes. Shoot for a single <h1>.
headings (with ids) Give your headings an id. It’s always
awesome. <h1 id=“the-beginning”>The Beginning</h1>
structure Make use of content sectioning elements: <nav> <header> <section>
<article> <aside> <figure> <footer>
css is for style Keep your html as clean as
possible (I know, I know). Try to avoid style attributes.
Beware the </div> How to build a slick marketing page:
1. Copy something from StartBootstrap 2. Strip out all the placeholder text. 3. Change the color scheme in CSS. 4. Publish, FTW!
validate Why in the world is HTML validation not built
into every single browser? Use the w3’s validator service or a browser extension.
be semantic The stuff in <html> describes a document. Everything
has meaning (or it should).
accessibility We should all learn more. Check out WAI-ARIA &
Section 508.
so… assuming html 5 what’s wrong with this code?
what’s wrong? <body> <div> <h2>Hello. </h2> <h5>there</h5> </div> </body>
what’s wrong? <p>Here's a <b>bold statement</b></p>
what’s wrong? <p> <font face="verdana" color=“green"> This is some text!</font>
</p>
what’s wrong? <i> <p>This paragraph is in italics!</p> </i>
what’s wrong? <big> <p>This paragraph is in italics!</p> </big>

of this Term. </p> <p> <strong>Other Term:</strong> Here's the meaning of this Other Term. </p>
what’s wrong? <div style="text-align:center"> This text will be centered. <p>So
will this paragraph.</p> </div>
what’s wrong? <script defer> console.log("Why won't this ever run!?"); </scrip>
what’s wrong? <a href="/report/" download=“report.pdf"> Download our Report </a>
