Inspect & Debug

CSS Inspector

Click any element to see its computed styles, then edit them live with sliders and colour pickers. Change padding, colours, fonts, borders and shadows on a real page and watch the result instantly — no DevTools panel required.

When you'd use it

• Check a built page against the design spec without opening a full DevTools panel
• Try three padding values on a card and see which one actually looks right in context
• Work out why an element has unexpected spacing by reading its computed box model
• Show a client a colour or type change live on their own site before quoting the work

How to use CSS Inspector

1. Open the UltraDevKit popup and choose CSS Inspector.
2. Hover the page — each element highlights with its dimensions and key styles.
3. Click an element to pin it and open the editing panel.
4. Drag the sliders or use the colour pickers; the page updates as you drag.
5. Copy the resulting CSS, or press Escape to discard every change.

CSS Inspector FAQ

Does editing CSS here change the real website?

No. Every change is local to your browser tab and disappears on reload. Nothing is saved to the server and no other visitor sees it.

How is this different from Chrome DevTools?

DevTools is more powerful but slower for visual work — you open a panel, find the element in the tree, then hunt through computed styles. Here you click the element on the page and get sliders for the properties you usually want to change.
