What are we going to learn today?[edit]

Hello Class!

Today in class we will:

we will have a surprise formative check: links and HTML
we will learn a bit about a very important concept: debugging

we will learn some basics about CSS, styling a webage
we will review the difference between HTML and CSS
we will learn about selectors, using this helpful tool: https://www.w3schools.com/cssref/trysel.asp
We will learn about properties, using this link: https://www.w3schools.com/cssref/
we will code a simple CSS file^[1]:

<!DOCTYPE html>
<html>
<head>
<style>
div {
    background-color: lightgrey;
    width: 300px;
    border: 25px solid green;
    padding: 25px;
    margin: 25px;
}
</style>
</head>
<body>

<h2>Demonstrating the Box Model</h2>

<p>The CSS box model is essentially a box that wraps around every HTML element. It consists of: borders, padding, margins, and the actual content.</p>

<div>This text is the actual content of the box. We have added a 25px padding, 25px margin and a 25px green border. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</div>

</body>
</html>

We will then review the box model in CSS using this code as a template.
We will learn linking to other documents
We will learn to use google chrome inspector to see what element we are working on

<!DOCTYPE html>
<html>
<head>
<style>
div.container {
    width: 100%;
    border: 1px solid gray;
}

header, footer {
    padding: 1em;
    color: white;
    background-color: black;
    clear: left;
    text-align: center;
}

nav {
    float: left;
    max-width: 160px;
    margin: 0;
    padding: 1em;
}

nav ul {
    list-style-type: none;
    padding: 0;
}
   
nav ul a {
    text-decoration: none;
}

article {
    margin-left: 170px;
    border-left: 1px solid gray;
    padding: 1em;
    overflow: hidden;
}
</style>
</head>
<body>

How am I being assessed today?[edit]

I will assess you formatively today, and make a professional judgement to what extent you understand our learning material. I will use observation, your written work, answers to questions, and contribution to class discussions as data to make my decisions. I normally record my observations in a "evidence of learning" spreadsheet, which I will happily share with you privately if you so wish. I usually need a day or two notice.

Standards we are covering today[edit]

As a computer scientist, you have:[edit]

Confidence in dealing with complexity
Persistence in working with difficult problems
Tolerance for ambiguity
The ability to deal with open-ended problems
The ability to communicate and work with others to achieve a common goal or solution
