##HTML and CSS

Without looking it up, create the basic HTML template structure with Doctype, head, title, and body

<!DOCTYPE html>

<head>
<title></title>
</head>

<body></body>


Write the HTML to add a link to google.com

<a href="https://www.google.com>Google</a>


Link to an external sheet at the path "css/styles.css"

<link href="/css/styles.css" rel="stylesheet"> 


Why do we want to use external stylesheets and scripts instead of adding them directly into our HTML file?

When you want to add style to multiple pages, so you do not have to re-add the same style to mutltiple pages 


What's the difference between a class and an ID?  Why do we use them?

id = used once / specifically identifies 
class = used multiple times

Using the following HTML:
<h1>Hello Guys!</h1>
<p>Don't Mess This Quiz Up!!!</p>
<div>
  <p>I'm a paragraph!</p>
  <p class="lol">I have a class!</p>
  <p id="wdi">I have an ID!</p>
</div>

Write CSS to change the color of the <h1>

h1 {
color: blue;
}


Write CSS to give the <p> with the id of 'wdi' a different font size

p.wdi {
font-size: 22px;
}

.wdi {
}


Write CSS to give the <p> with the class of 'lol' a background color.

p.lol {
background-color: 000;
}


Write CSS to give the first <p> in the <div> a yellow border.

div {
border color:
}


Name at least two of the different color formats used in CSS

RGB and RGBA

##Optional Bonus
If you finish early, work on this problem:
Using either Ruby or Javascript, write code that will test if a given string is a palindrome.  A palindrome is a word that is the same forwards and backwards, like 'mom' or 'racecar' or 'aibohphobia'.  You are not allowed to use the built in reverse method or any similar methods.
