Inspect and live-edit the HTML and CSS of a page using the Chrome DevTools Elements panel.
- Inspect and edit on the fly any element in the DOM tree in the Elements panel.
- View and change the CSS rules applied to any selected element in the Styles pane.
- View and edit a selected element's box model in the Computed pane.
- View any changes made to your page locally in the Sources panel.
Live-edit a DOM node
To live-edit a DOM node, simply double-click a selected element and make changes:
Live-edit a style
Live-edit style property names and values in the Styles pane. All styles are editable, except the ones that are greyed out (as is the case with user agent stylesheets).
To edit a name or value, click on it, make your changes, and press Tab or Enter to save the change.
By default, your CSS modifications are not permanent, changes are lost when you reload the page. Set up persistent authoring if you want to persist your changes between page loads.
Examine and edit box model parameters
Examine and edit the current element's box model parameters using the Computed pane. All values in the box model are editable, just click on them.
The concentric rectangles contain the top, bottom, left, right values for the current element's padding, border, and margin properties.
For non-statically positioned elements, a position rectangle is also displayed, containing the values of the top, right, bottom, and left properties.
position: fixed and
position: absolute elements, the central
field contains the actual offsetWidth × offsetHeight pixel dimensions
of the selected element. All values can be modified by double-clicking
them, like property values in the Styles pane. The changes are not, however,
guaranteed to take effect, as this is subject to the concrete element
View local changes
To view a history of live-edits made to your page:
- In the Styles pane, click on the file that you modified. DevTools takes you to the Sources panel.
- Right-click on the file.
- Select Local modifications.
To explore the changes made:
- Expand top-level file names to view the time a modification occurred.
- Expand second-level items to view a diff (before and after) corresponding to the modification. A line with a pink background signifies a removal while a line with a green background signifies an addition.
If you haven't set up persistent authoring, any time you reload the page, all live-edits are lost.
Assuming you've set up persistent authoring, to undo changes:
Use Ctrl+Z (Windows) or Cmd+Z (Mac) to quickly undo minor changes to the DOM or styles via the Elements panel.
To undo all local modifications made to a file, open the Sources panel and select revert next to the filename.
