Study Community Survey:
"I'm officially employed as a full-time software engineer... well, technically, the role is "consultant" and the position is "software engineer"! Â I started my journey in Leon's last cohort as a single mom, an unemployed real estate agent during the pandemic, with two awesome kids, a noisy little dog, and a BIG DREAM.
Those of you on the other side of 40: you can do this. Listen to everything Leon tells you to do and then just do it. Those of you with family obligations: just keep going... take needed breaks, find support where you can get it. Those of you with mental health profiles: I hear you loud and clear (GAD/SAD, unmedicated). Neurodiverse folx: my peeps we're all in it together and we've got this!
There are so many people who helped me keep going, I don't want to name names because I'm sure I'll forget super-important folx (I'm on a lunch break and have to do tons of stuff). But I mean this sincerely: I am eternally grateful for my cohort friends and our amazing, dedicated teacher @Leon."
CONGRATS! OCC (Jennifer)!

The Golden Rule
SEPERATION OF CONCERNS
-
HTML = Content / Structure
-
CSS = Style
-
JS = Behavior / Interaction

Where does CSS go?

In the head

In a separate file
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
Â
What comes below, can override what came above
Â
This is called the Cascade
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 elementÂ
parent child
<section>
<article>
<p>Hello, Twitch!</p>
</article>
</section>Selecting By Relationship
p + p {
color: red;
}To select an element that is the next sibling use
Â
previous sibling + next sibling
<section>
<p>Hello, Twitch!</p>
<p>Hello, Youtube!</p>
</section>IDs & Classes
IDs
#zebra {
color: red;
}IDs are used for selecting distinct elements

</section>Classes
