Some samples that need repairs

1. Structure

Infuse meaning in a meaningless thing.

Many different techniques are possible.
2. Images

Make images perceptible

Also many different techniques, such luck!
3. Contrast

Trusting your intuitions.

Because intuition is never wrong.
4. Reflow/responsiveness

No one is doing this sort of thing anymore, right?

Specially since there are so many alternatives.
5. Focus order

An experiment in disorentation

That is all.
6. Visible focus

Another experiment in disorentation

That is all.
7. Broken keyboard

A series of bungled keyboard controls

That is all.
8. Keyboard

Native and non-native controls responding to keyboard

That is all.
9. Links

The oldest, simplest web control element.

Should be really simple, right?
10. Forms: structure

Visual and logical structure makes everyone happy.

People are so easy to please.
11. Forms: names

Do not leave your controls without a name.

Perhaps one of the more important things to get right.
12. Forms: other form things

Everything in a form needs to be related to form elements.

There is unfortunately a lot of subtlety to this.
13. Forms: front end validation

Front end validation has some special requirements.

There are only a few good patterns, and some browser complications.
