Devices and their Fickle Owners

Lecture outline

Thinking about how users use websites, and more options for laying out your site. Lecture slides will be made available on the day of the lecture (June 7).

Critique prep

Please come and sign-up for a timeslot for critique. I will briefly cover alternative activities you can partake in during critique time at 9:45, after which we will reconvene for lecture at 11:30.

Please make sure to have materials ready for critique when your timeslot comes up.

Points on breakpoints

How to aim for optimal breakpoints?

• Let your content decide
• Use relative units (always)
• Avoid an absolute process

Progressive enhancement

Build up from the basics

The layering of progressive enhancement:

• Content: Ensuring that the basic content works (clean, semantic, HTML).
• Styling: Applying styling and testing across devices (caniuse.com).
• Scripting: Enhancing the experience as much as possible.

Advanced progressive enhancement

(aka. Responsive Web Design)

We are taking a device-agnostic approach, as the screen isn't our only variable:

• Problematic browsers
• Slow connections
• Small screens
• Touch first
• Content structure
• ... etc.

Degredation vs. enhancement

Wait, so what's different?

Graceful degredation: Build for the biggest and bestest, making sure that the site is still usable for 'lower-class' browsers.

Progressive enhancement: Build a common standard for all browsers (upper and lower class), then offer additional functionality for browsers which can use it.

What should my site look like?

Consider the patterns.

Remember, your site should:

• Clearly indicate interactivity (like a link)
• Help your user achieve their goals
• Provide them with the content and tools to achieve their goals

Consistency

Internal vs. external

Internal consistency is consistency between the elements within your own site, while external consistency is consistency between the elements of your site with other websites.

Responsive images

Thinking about when and how to use responsive images includes a variety of factors:

• User's resolution or screen sizes
• Dimensions of the image
• Breakpoints

Sizing images

When sizing images, consider the maximum pixel dimension the image would be displayed at and the possible pixel density of the device.

Positioning

One way to move things on the web

Some options:

• static — the default, things occur as ordered in the HTML
• relative — similar to static, but allows for further instructions through 'left', 'right', 'top', 'bottom' to move relative to its original position
• absolute — positions relative to the viewport through 'left', 'right', 'top', 'bottom'
• fixed — similar to absolute, but will not scroll (stays in view)
• sticky — fixed within container, relative otherwise
