A user interface needs clear zones for content and controls.
Sticky elements ensure important tools are always visible. Careful management of overlapping elements prevents visual clutter.
A developer should use a two-zone layout. One zone allows content to grow or shrink. The second zone keeps its size fixed. Input controls should stay at the bottom of the screen. This makes them always available to the user. A developer must use specific CSS properties for this. These properties include `position: sticky`, `bottom: 0`, and `z-index: 10`. A background color is also important. A status bar should be 28 pixels high. It can contain two elements that overlap. One element is for milestones. The other is for status text. The status text should hide when it is empty. This reveals the milestone information. The main content area needs padding at the bottom. This prevents content from hiding behind sticky elements. Right-side panels should float over the main content. They should not be part of the main layout flow. A developer must close all other right panels before opening a new one. History search should happen on the server. This is faster and more efficient. Every interaction with the AI model should track costs. This helps manage resources. Developers should add comments to their code. These comments should include the date of changes.
A developer is building an AI chat application. The developer uses a two-zone layout. The chat history is in the flexible zone. The input box is in the fixed zone at the bottom. The input box uses `position: sticky` so it never scrolls away. A small status bar shows if the AI is typing. When the AI finishes, the status text disappears. A 'cost' counter updates after each AI response. This helps the manager track expenses. The developer adds a date comment to the code after fixing a bug.

A developer should check all existing rules that might be affected. This check must happen before adding any new standardized rule.
A developer should list all problems. Group similar problems together.
Inconsistent CSS means that design elements look different across a website or application. For example, buttons might have different rounded corners or spacing.
Realistic diagrams often have parts that overlap. For example, a bicycle bell sits on a handlebar.
