Hi Leon,

 

It was a pleasure meeting you last night! The event was so well done and it was exciting meeting such an amazing group of people - I hope you are enjoying a well deserved break after pulling it all together!

 

Also, I don't know if you saw this yet, but someone just bought a $375k first edition pokemon booster box and it wound up being fake! The Gaurdian covered it and I remember you mentioned being a big fan. Hope you have a great rest of the week!

 

Cheers,

Bob

Hi Leon,

It was a pleasure meeting you last night! The event was so well done and it was exciting meeting such an amazing group of people - I hope you are enjoying a well deserved break after pulling it all together!

 

As I mentioned last night, I'm just starting my engineering career and would love to learn from successful people such as yourself. Please let me know if there might be a time you are free to grab a virtual coffee over the next week or two. Before 9am or after 5pm tends to work best for me, but happy to accommodate what works for you. Thanks!

 

Also, I don't know if you saw this yet, but someone just bought a $375k first edition pokemon booster box and it wound up being fake! The Gaurdian covered it and I remember you mentioned being a big fan. Have a great rest of the week!

 

Cheers,

Bob

The Golden Rule

SEPERATION OF CONCERNS

  • HTML = Content / Structure

  • CSS = Style

  • JS = Behavior / Interaction

Progressive Enhancement

According to the United States Department of Commerce, about 22 million Americans--roughly 35% of the nation's rural residents--lack access to broadband.

CSS

Where does CSS go?

  • Inline

  • 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

 

What comes below, can override what came above

 

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 element 

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

 

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

Only one id with the same value per document

#idName

<section>
  <p>Hello, Twitch!</p>
  <p id="zebra">Hello, Youtube!</p>
</section>

Classes

.bob {
  color: red;
}

Classes are for selecting multiple elements

Multiple with same value allowed per document

.className

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

Specificity

#pizza p span.gone {
  color: red;
}
<section id="pizza">
  <p class="jumanjiOriginalMovie">Hello, Twitch!</p>
  <p id="car" class="hello">Hello, Youtube!</p>
  <p>Goodbye, <span class="gone">Mixer!</span></p>
</section>

Specificity

#dietCoke p.robot.unicorn + .bob {
  color: red;
}
<section id="dietCoke">
  <p class="robot unicorn">Hello, Twitch!</p>
  <p id="zebra" class="bob dominosPizza">Hello, Youtube!</p>
  <p class="bob">Goodbye, Mixer!</p>
</section>

Specificity

#dietCoke > .robot + .dominosPizza + .bob {
  color: red !important;
}
<section id="dietCoke">
  <p class="robot unicorn">Hello, Twitch!</p>
  <p id="zebra" class="bob dominosPizza">Hello, Youtube!</p>
