The Golden Ratio in UI Design
The Golden Ratio (1.618) is a proportion from art and nature used to create visually harmonious UI. Apply it to set layout dimensions or create a typographic scale (e.g., a 26px header for 16px body text).
Modular Grid: Organizing UI with Cells, Not Just Columns
Think of a modular grid as spreadsheet cells for your UI. It extends a column grid with horizontal rows, creating a matrix of modules. It's ideal for repeating items like product cards or dashboard widgets.
Focal Point: You Can't Emphasize Everything
A focal point guides the user's eye by making one element dominant. To make something stand out, other elements must fade into the background. Use it to draw attention to a call-to-action or headline. The footgun is trying to emphasize everything at once.
Semantic Naming for Design Tokens
Don't name a token by its value (`blue-500`); name it by its job (`color.action.primary`). This decouples design intent from implementation, making systems scalable. It's key for theming and avoiding "lie" variables when designs change.

Icon System Design: Build Once, Use Everywhere
Treat icons as reusable building blocks, not one-off graphics. A systematic setup in Figma ensures consistency and speeds up your entire design process. The footgun is skipping standardization, which creates tedious overrides and visual debt later on.
SVG: Code-Based, Infinitely Scalable Graphics
Think of SVG as HTML for graphics. It's an XML file with drawing instructions, not pixels, so images scale perfectly. It's ideal for logos and icons on responsive sites. The footgun: SVGs can contain JavaScript, posing a security risk (XSS) if not sanitized.
Rule of Thirds: Guide the Eye, Don't Just Center
Don't center your subject; place key elements along the lines or intersections of a 3x3 grid. This creates a more dynamic, visually interesting composition in photos and UI layouts. The footgun is treating it as a rigid law; sometimes centering is better.
RGB vs. HSL: Two Ways to Tell a Computer 'Color'
RGB tells a computer how to mix light (Red, Green, Blue), while HSL describes color how humans perceive it (Hue, Saturation, Lightness). Use RGB for brand colors and HSL for intuitive variations. The footgun is creating low-contrast UIs that are unreadable.
Cognitive Load: Don't Make Users Think (Too Hard)
Think of a user's brain like a computer with limited RAM; cognitive load is the processing power your UI demands. High load from cluttered interfaces slows users down, causing them to miss details or abandon tasks.
Jakob's Law: Don't Reinvent the UI Wheel
Users spend most of their time on other sites, so they expect yours to work like everything else they already know. Leverage familiar patterns for navigation, icons, and workflows.
Visual Hierarchy: Guiding the User's Eye
Visual hierarchy guides the user's eye by making important things look important. It uses contrast in size, color, and placement to create a path of importance, like a big headline versus small footer text.
Nielsen's 10 Heuristics: Rules of Thumb for UI Design
Nielsen's Heuristics are ten rules of thumb for evaluating if a design is user-friendly. Use them to spot usability issues in any interface, from apps to stovetops. The biggest mistake is treating them as strict laws, not flexible guidelines.
