Or we can translate them into position using transform. we can position: absolute them and offset them with the top and left properties. cells in a container, because if we do, the. cell must come before the element we want to control (in this case, the. square, and the way the cascade works (for now) is that an element can only control its children (or descendants) and its siblings (or their descendants) - but only as long as the sibling is after the controlling element. Suprisingly I forgot how to get the X and Y coordinates of mouse. Example 1: This example implements the above approach. Yesterday while working on a script and I wanted to know the cursor X, Y coordinates. Use document.elementFromPoint (x, y) method to get the element content on that position when mouse pointer moves over. (And yes, it’s OK to use Pug for that, even though I won’t in this example.) There are two approaches to solve this problem which are discussed below: Approach 1: Get the x and y coordinates value by using. It’s important to maintain proper balance and adjust the grid size to the specific needs of each project.įor now, lets say that we want a 10×10 grid for a total of 100 cells in our markup. But that also means we will have more cells, which can lead to performance issues. The larger it is, the more accurate our custom property values will be. We’ll do the same with -positionY: the value will be lower as the cursor moves to the top, and higher when it moves to the bottom.Ī few words about the grid size we’re using: We can actually make the grid whatever size we want. So, when the mouse cursor moves to the right side of the screen, the value of the -positionX will be higher and when it moves to left, it gets lower. The goal is to create an invisible grid on the screen, and use the :hover pseudo-class to map each ‘cell’ to a set of values that we will allocate to the custom properties. We’ll see some of these bonus demos at the end of the article. For example, we could use them to set the top / left properties of an absolute positioned element, control a transform property, set the background-position, manipulate colors, or even set the content of a pseudo-element. Once we have mapped the custom properties for mouse position, we can use them to do pretty much anything we want. ![]() square element’s width and height accordingly. we will use the mouse position to set the value of these properties, and then use them set the. We’ve also added the two custom-properties to the content. This will host the content of our project, and the elements we want to control using the mouse position – in this case, the. content class of that is spread to the width and height of the body. Then event.currentTarget will do the trick.Heads up that we’re only using SCSS here for brevity, but all of this can be done in pure CSS. If you use event.target and hover your mouse over div2, you will get relative coordinates regarding div2 while you might want them to be regarding div0. It makes the difference when you want to attach a listener to some element that has multiple children. event.currentTarget is the element that the event listener is attached to.event.target is the element that triggered the event (e.g., the user clicked on or hovered on).Now x and y are the relative coordinates. ![]() ![]() I recommend using currentTarget instead of target: const handleEvent = (event) =>Ĭonst bounds = () So far I have this function onMousemove(event) Īlthough the answer of Nikita Volkov is pretty solid, it might not work as expected in some cases. I am trying to get the mouse position relative to the div with the id container. I currently have a div structured with other elements inside of it.
