CSS inspection is looking under the hood of a webpage to see what styles are actually applied to an element. During design QA, it answers questions like: What font size is this? Why is there extra space here? Which CSS rule is making this blue?
When you need CSS inspection
- Design QA: Verifying that implemented styles match the design file
- Bug hunting: Finding why an element looks wrong
- Handoff notes: Documenting exact values for developers to change
- Learning: Understanding how a site achieves a particular look
What CSS inspection reveals
- Typography: font-family, font-size, font-weight, line-height, letter-spacing
- Spacing: margin, padding, gap
- Colors: color, background-color, border-color
- Layout: display, position, flexbox/grid properties
- Box model: width, height, border, box-sizing
- Computed values: The final resolved values after all CSS rules are applied
Traditional CSS inspection
Browser DevTools (right-click → Inspect) show CSS for any element. Powerful but complex—you're wading through inherited styles, overridden rules, and browser defaults to find what you need.
For quick checks during a review, DevTools can feel like overkill.
Lightweight CSS inspection
Some tools surface the most-needed properties (font, color, spacing) in a simpler interface. Click an element, see its key styles instantly, without the full DevTools panel.
CSS inspection in Huddlekit
Huddlekit's inspect mode shows typography, spacing, and color values with a single click—no DevTools required. Pin a comment while the values are visible, so your feedback includes the exact CSS context. Developers see "font-size: 14px, should be 16px" instead of "text looks small."
