A developer must check many things when changing a user interface.
Changes can affect how elements look and how a user interacts with them. Careful testing prevents new problems.
First, read the main file for the user interface. Identify the specific part of the interface to change. Check if the change will make the element taller or shorter. This includes changes to text, spacing, or visibility. If the height changes, use a fixed-slot method. This means using 'position: relative' for the parent and 'position: absolute' for child elements. Calculate the total height of the affected area. The height must remain the same, for example, 166 pixels. Verify the design fits in a small screen. For example, it must fit within 552 pixels of height. Test the full user process from start to finish. This includes typing, clicking buttons, seeing loading, and getting results. Test how the change works with other parts of the interface. For example, change a setting and check if the layout shifts. Generate content multiple times to see if reminders appear correctly. Check if warning messages appear without shifting other elements. Confirm that important information, like a footer, is always visible. Check that buttons show the correct state at each step of a process. Ensure that horizontal bars do not break into new lines. Get clear approval from a user before saving the changes.
A developer changes the font size of a button. This change makes the button taller. The developer must check if the button now overlaps other elements. The developer must also test if the entire form still fits on a small phone screen. If not, the developer must adjust the layout to prevent overlapping or cutting off content.

A developer must follow specific rules for layout. The entire screen should be visible without scrolling.
The user interface for Chapter 1 is the master design. All other chapters must use this design.
All web pages must use the same brand colors. Do not create new color schemes.
