Styling the Webs

Lecture outline

Thinking about our websites as modular components and the fundamentals of styling websites. Lecture slides will be made available on the day of the lecture (May 17).

Extra IAT-235 bridging support

We recognize that some of you may not have gotten much time working with HTML and CSS in IAT-235. If you need additional support getting up to speed please reach out to us.

I will be on Discord most Tuesdays and Thursdays if you have quick questions or concerns.

Lecture recordings

Lecture recordings are connected to the slide decks.

As this is a new build please let me know if you encounter any problems loading or viewing the recordings.

We want to try and move away from the language of 'pages'

Web design and development

You have to learn to embrace flexibility, failure and iteration.

How do users use the web?

Cascading Style Sheets

While HTML defines the structure of the content on the page, CSS styles the page to ensure the user get's something usable. Good code will clearly separate semantic markup from styling.

Keeping them apart

A real Romeo/Juliet scenario

Rules for keeping them separate

Smart CSS

You want to aim for CSS stylings that are scalable and modular. Here are some divisions suggested as a framework:

  1. Base rules: direct styling of elements for normalizing or defaults
  2. Layout: structural styling for the page (i.e. .grid, .grid-column)
  3. Modules: styling for different components (i.e. .nav-bar, .nav-button)
  4. State Rules: styling different states (i.e. .is-current, .is-opened)

Coding conventions

ID vs. class

IDs must always be unique, <section id="kittens"> they can only be specified once. While classes can be used as many times as needed<section class="group">


The order in which things are read

  1. Inline styles: should never be used
  2. ID's: #home, #cool-stuff
  3. Classes, attributes & pseudo-classes: .home, [class], :hover

Units in CSS

In the journey to responsiveness, we want to aim for relative and scalable units as much as possible.


Rems — root-ems — are units responsive to the font-size set by the browser which help us establish easy relationships in type.

Developer tools

Your new best friend

Ever wanted to know what the slides would look like with a red background? Right-click and 'Inspect Element' opens up the development tools to mess around with things in.

The display property

Block, inline, and inline-block

Block elements break to the next line, can have a height and width, and by default are full-width.

Block One
Second Block

Inline elements stay in-line with other inline elements, and listen to their content for their sizing.

Inline One
Second Block

Inline-block elemetns stay in-line with other inline elements, can have a height and width, and listen to their content for their sizing.

Why we care

At the end of the day, it's about your mental sanity. But good clean, clear coding conventions, page and file structure typically loads and runs faster.

Some things to think about

You are not required to generate your own images and icons for this project. That being said, the branding must still be your own work. Here are some recommended suggestions:
