# Stoplight Exercise As always, fork and clone this repo. ![Screenshot of the stop bulb lit up](screenshot.png) ## Part 1 Add DOM event listeners to toggle the on/off state of three bulbs. - When a user clicks on the "Stop" button, the top bulb should turn `red`. - When a user clicks on the "Slow" button, the middle bulb should turn `orange`. - When a user clicks on the "Go" button, the bottom bulb should turn `green`. **TIP**: All three bulbs can be on/off independently of one another. ### Resources - [MDN - `Document.querySelector()`](https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelector) - [MDN - `EventTarget.addEventListener()`](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener) - [MDN - `click`](https://developer.mozilla.org/en-US/docs/Web/Events/click) - [MDN - `background-color`](https://developer.mozilla.org/en-US/docs/Web/CSS/background-color) ## Part 2 Add new DOM event listeners to log the mouse state of each button. - When a user's mouse "enters" a button, log `"Entered button"` to the console. - When a user's mouse "leaves" a button, log `"Left button"` to the console. ### Resources - [MDN - `mouseenter`](https://developer.mozilla.org/en-US/docs/Web/Events/mouseenter) - [MDN - `mouseleave`](https://developer.mozilla.org/en-US/docs/Web/Events/mouseleave) ## Bonus Add **one** new DOM event listener to log the state of each bulb. - When a user clicks a button that just turned on, log`" bulb on"` to the console. - When a user clicks a button that just turned off, log`" bulb off"` to the console. **TIP:** Make sure only a button click causes a message to be logged to the console.
