How to Debug CSS Issues Using Chrome DevTools

· Category: VS Code & Developer Tools

Short answer

DevTools lets you inspect applied styles, toggle properties, and visualize the box model. This makes it easy to spot specificity conflicts, missing units, and layout errors.

Steps

  1. Right-click an element and select Inspect to open the Elements panel.
  2. In the Styles pane, view all CSS rules affecting the element.
  3. Toggle individual properties on and off by clicking the checkbox next to them.
  4. Edit values directly to test fixes in real time.
  5. Check the Computed tab to see the final resolved values.

Tips

  • Use the color picker and shadow editor in the Styles pane for visual adjustments.
  • The Layout pane shows CSS Grid and Flexbox overlays.
  • Badges next to rules indicate if a property is inactive or overridden.

Common issues

  • Inline styles often override external CSS due to higher specificity.
  • Changes in DevTools are not persistent; copy fixes back to your source code.
