Where does CSS go?

  • Inline

  • In the head

  • In a separate file

CSS

Use a separate CSS file

It is best practice to put CSS in it's own file and link to it from the <head> !

 

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

CSS BREAK DOWN

p{
  color: red;
  font-weight: bold;
}

The whole thing is called a rule.

The p is called a selector.

It is followed by a set of declarations in a declaration block

CSS BREAK DOWN

p{
  color: red;
  font-weight: bold;
}

What is this?

p{
  color: red;
  font-weight: bold;
}
p{
  color: blue;
}

CSS is read top to bottom

 

What comes below, can override what came above

 

This is called the Cascade

CSS BREAK DOWN

Why might we want to link to a separate CSS file?

Some Basic CSS

Selecting By Relationship

section > p {
  color: red;
}

To select an element that is the direct descendent of another element use

parent > child

<section>
  <p>Hello, Twitch!</p>
</section>

Selecting By Relationship

section p {
  color: red;
}

To select an element that is inside of another element without being directly descended use parent element 

parent child

  </article>
</section>

Selecting By Relationship

p + p {
  color: red;
}

Classes

.bob {
  color: red;
}

Classes are for selecting multiple elements

Multiple with same value allowed per document

  <p id="zebra" class="bob">Hello, Youtube!</p>
  <p class="bob">Goodbye, Mixer!</p>
