Highlight DOM Elements On Hover – TheRoom


TheRoom is a JavaScript plugin that applies a customizable overlay effect to any DOM elements on hover.

Also provides the ability to display the current selector (tag, id, and class) you’re viewing on, similar to the web inspector.

You can also specify the DOM elements to exclude.

How to use it:

1. Download and import the ‘theroom.js’ into the document.

<script src="dist/theroom.min.js"></script>

2. Config and initialize the TheRoom library. That’s it.

  // options here

3. Full plugin options to config the TheRoom

  // string or DOM node of the inspector
  inspector: null,
  // If true and inspector option is not provided, theRoom will try to create an inspector element whose class is inspector-element for you and will be appended to body tag
  createInspector: false,
  // add the theRoom's namespace to html tag
  htmlClass: true,
  // block page direction
  blockRedirection: false,
  // exclude elements here
  excludes: []

4. More API methods.

// stop
// get status

5. Event handlers.

window.theRoom.on('mouseover', function (element) {
  // do something
window.theRoom.on('starting', function (element) {
  // do something
window.theRoom.on('started', function (element) {
  // do something
window.theRoom.on('stopping', function (element) {
  // do something
window.theRoom.on('stopped', function (element) {
  // do something
window.theRoom.on('click', function (element) {
  // do something
window.theRoom.on('hook', function (element) {
  // do something
