About you - ‘round the room
• What’s your name?
• What’s your programming background?
• What’s your goal?
Goals
• Core concepts of HTML/CSS to build websites
• Drills to practice those concepts
• Build your first website
• Get more comfortable learning to code
• Take home challenges
How the web works
Type a URL from a client (e.g. google.com)
Browser communicates with DNS server to
find IP address
Browser sends an HTTP request asking
for specific files
Browser receives those files and renders
them as a website
Clients / Servers
Client (sends requests)
Frontend Developer
Manages what user sees
Server (sends response)
Backend Developer
Manage what app does
How it relates to what we’re doing
When we write HTML & CSS today, we are creating
those files that are stored on a server which are then
sent and then rendered by your browser
Setup
http://bit.ly/tf-html-classroom
Normally to write our code we’d use a text editor or an
integrated development environment (IDE)
But since we’re learning we’re going to write our code
in a website to skip the setup, see our results
immediately, and make it easy for us to track progress
Let’s start with HTML
HTML is the content and structure of a webpage
It’s the skeleton of your website
By itself, HTML is ugly
We’ll make it pretty later
We will start with just HTML — we’ll then add a
Cascading Style Sheet (CSS) file to “style” our
website. More on that later…
Your first website
Copy this code (don’t worry if you don’t understand it)
<html>
<body>
<h1>Hello world!</h1>
</body>
</html>
Key HTML concepts
• Tags
• Elements
• Attributes
HTML tags
Every tag starts with a “less than” sign and ends with a
“greater than” sign
<html> #this is an HTML opening tag
<body> #this is a body opening tag
<h1>Hello world!</h1> #this is set of
H1 tags
</body> #this is a body closing tag
</html> #this is an HTML closing tag
More about tags
• There are opening tags and closing tags — closing tags
have a backslash before the tag name (</html> versus
<html>)
• Tags instruct a browser about the structure of our
website
• There are hundreds of built-in tags though you’ll use
the same few a lot
Non-exhaustive list of HTML tags
• <html> #html tags wrap your entire page
• <head> #head tags holds info about the page
• <body> #body tags wrap around your content
• <h1> #signifies the largest headline (through h6)
• <p> #wraps a paragraph of writing
• <div> #div tags are generic container tags
• <a> #anchor tags for text to be a link
• <ul><li> #unordered list of items
• <button> #this is a button
HTML elements
HTML elements usually consist of an opening tag,
closing tag, and some content
<html> #html element starts here
<body> #body element starts here
<h1>Hello world!</h1> #this is an
HTML element
</body> #body element ends here
</html> #html element ends here
More about elements
Some consist of just a self-closing tag
<img src=“http://i.imgur.com/Th5404r.jpg">
A note about <div>’s
We use <div> tags to separate sections of our site. This
will allow for sophisticated styling. It’s a good habit to
“wrap” most sections into a <div>
<div>
<h1>Hello world!</h1>
</div>
HTML attributes
HTML attributes set properties on an element — the are
attached in the opening tag
<a href=“https://somewhere.com">This is a
link</a>
href is an attribute that sets the destination of a link
<h1 class=“headline”>This is a headline</h1>
class is one attribute that identifies element (for CSS &
Javascript)
HTML Challenges
Complete the following assignments on
http://bit.ly/tf-html-classroom

What is CSS?
Cascading Style Sheets (CSS) interact with your HTML
to determine the visual presentation of your webpages
CSS example
p {
color: red;
font-size: 36px;
}
CSS solves two problems
• Visual presentation of each element
• Layout of elements
Key CSS concepts
• Selectors
• Property
• Value
• Declaration / Declaration Block
CSS selectors
• Determine HTML elements to target for styles
• Can target tags, classes, id’s and many more!
• Selectors can be combined
Example selectors
p (selects all paragraph tags)
.name (selects HTML elements with class “name”)
p.name (selects paragraph tags with class “name”)
CSS properties
Determines aspect of an element’s appearance to change
• color (set the font color)
• font-family (sets main and backup typefaces)
• background-image (sets background image)
• height (sets the height of an element)
More on CSS properties
• Each property has a default value — when you write
CSS, you override that default with a new value
• There are lots of CSS properties! For a full list see
http://www.htmldog.com/references/css/properties/
CSS values
Determines the aspect of the element’s appearance we
wish to change
• color: red, blue, green, #CCCCCC
acceptable values for the color property
• font-family: helvetica, arial, sans-serif
acceptable values for the font-family property
• background-image: url(“imageFile.jpg")
looks for a URL value for image file
• height: 40px, 50%
set in pixels or percentage of container height
Declarations and declaration blocks
This is a declaration block containing two declarations
p {
color: red;
font-size: 36px;
}
CSS challenges
Complete the following assignments on
http://bit.ly/tf-html-classroom
• Selectors
• Classes
Linking CSS to HTML
• Normally you’d have one HTML file for each webpage
(for example, home.html and profile.html), and a single
CSS file for the whole website’s styles (styles.css)
• To link your stylesheet to your HTML, you’d insert the
following line into the <head> section of your HTML
webpage
• <link rel="stylesheet" type="text/css"
href="theme.css">
Learning to learn
• Google is your friend!
• Practice at the edge of your abilities
• Ignore the hot new thing. Instead go deep with one
technology
