# Web Devlopment Workshop
</section>
<section data-markdown>
##HTML
HTML stands for HyperText Markup Language. It is the "hidden" code that we use to communicate
with others on the World Wide Web. When we write HTML code, we add "tags" that help to create
the structure of the page; tags tell the web browser just how to display the content of the
html document.
</section>
<section data-markdown>
### Syntax
Syntax is another word for grammar. Because computers are very literal machines,
we must use "good" syntax in our code.
</section>
<section>
<section data-markdown>
### Specific Tags
Tags are angled brackets that look like this <... >, with some letters or word inside
them. These brackets are on your keyboard, over the comma and the period. We type
words into these brackets to tell the computer what to do.
</section>
<section data-markdown>
- The `div` tag defines a division or section in an HTML document
- The `p` tag defines a paragraph
- The `img` tag defines an image
- The `a` tag defines a hyperlink
- The `ul` tag defines an unordered list
- The `li` tag defines a list item
</section>
</section>
<section data-markdown>
### Exercise
Go to `practice/ex-1/index.html` and build a webpage using the skills you just learned. Tell us a little about yourself!
</section>
<section data-markdown>
##CSS
</section>
<section>
<section data-markdown>
### The CSS Rule Set
</section>
<section data-markdown>
#### Selector
We use the selector to tell the computer what part (or parts) of our HTML we want to change with this CSS rule. A selector can be as simple as using the name of a tag or it can be very complex and specific.
```css
div {
}
```
</section>
<section data-markdown>
#### Property
The property is the thing about the selected element (or elements) that we want to change. There are _tons_ of these and I don't expect you to remember most of them. We'll talk about some very commonly-used ones to get you started.
```css
div {
background-color:
}
```
</section>
<section data-markdown>
#### Value
If the property is the aspect we want to change, the value is what we want to change it _to_.
```css
div {
background-color: blue;
}
```
</section>
<section data-markdown>
#### Bringing It All Together
- There's a colon (`:`) between properties and their values.
- Property/value pairs are separated with a semi-colon (`;`).
- We can have as many property/value pairs as we want, but we have to surround them with curly braces (`{}`).
```css
div {
background-color: blue;
color: limegreen;
font-size: 20px;
}
```
</section>
</section>
<section>
<section data-markdown>
### background
</section>
<section data-markdown>
#### What it Does
The `background` property is a quick way to change lots of different things related to the background of our web page's elements.
```css
div {
background-color: blue;
}
```
</section>
</section>
<section>
<section data-markdown>
### color
</section>
<section data-markdown>
#### What it Does
The `color` property changes the color of the _text_ inside the selected element.
```css
div {
color: limegreen;
}
```
</section>
</section>
<section>
<section data-markdown>
### width
</section>
<section data-markdown>
#### What it Does
We can use the `width` property to change the width of elements. By default, block elements like `p`s and `div`s will take up the full width of their parent elements.
```css
div {
width: 500px;
}
```
</section>
</section>
<section>
<section data-markdown>
### font-size
</section>
<section data-markdown>
#### What it Does
The `font-size` property affects the size of text.
```css
div {
font-size: 20px;
}
```
</section>
</section>
<section data-markdown>
### Exercise
Let's try using the CSS properties we've learned about!
Go to `practice/ex-2/styles.css` and add some CSS. Feel free to play around with additional HTML, too!
</section>
<section>
<section data-markdown>
### Specifying Color
</section>
<section data-markdown>
#### Keywords
Probably the easiest and fastest way to pick a color in CSS is to use a keyword. However, the available colors are limited. We can't be very exact in our color choices.
See this [list of available color names](http://www.crockford.com/wrrrld/color.html).
```css
div {
background-color: salmon;
}
```
</section>
<section data-markdown>
#### Hex Codes
Short for "hexadecimal codes", hex codes give us much more control over our color choices. Hex codes start with a pound symbol which is followed by six characters (0-9, A-F).
This [color picker](http://www.colorpicker.com/) will tell you what the hex code is for any color you choose.
```css
div {
background-color: #bcdfbb;
}
```
</section>
<section data-markdown>
#### RGBA
RGBA allows us to make the color transparent. We'll have to use four values: the amount of red, green, and blue the color we want contains (0-255), then a number from 0 to 1 to represent how transparent the color should be.
```css
div {
background-color: rgba(41, 133, 163, 0.6);
}
```
</section>
</section>
<section data-markdown>
### Exercise
Go back to `practice/ex-2/styles.css` and add in some color!
</section>
<section data-markdown>
##JavaScript
</section>
<section>
<section data-markdown>
###What is JavaScript?
</section>
<section data-markdown>
JavaScript is a programming language, so it's a little different than anything we've talked about so far. It's used to make websites interactive.
</section>
<section data-markdown>
### Semi-colons
Semi-colons (`;`) are very, very important in programming! They're like the periods of JavaScript, so don't forget about them!
</section>
</section>
<section data-markdown>
### Variables
Variable are like boxes that we can put different kinds of data in to refer to them later.
```javascript
var name = "Aisha";
var age = 25;
var isHappy = true;
```
</section>
<section data-markdown>
## Arrays
Arrays hold collections of information.
```javascript
var colors = ["red", "orange", "yellow", "green", "blue"];
```
</section>
<section data-markdown>
## Objects
Objects are a more complicated way to store data. We'll need to use these later on!
```javascript
var student =
{
name: "Ben",
age: 25,
hobbies: ["video games", "programming", "D & D"];
};
```
</section>
<section data-markdown>
## Functions
Functions allow us to package up our code and use it in other places.
```javascript
function sayHello(name) {
console.log("Hello, " + name + "!!");
}
```
</section>
<section>
<h3>Exercise</h3>
Go to [repl.it](https://repl.it/) and practice what we've just learned!
