Hi Folks,
Before diving into the project, a little bit of introduction about me:
I am Sabiya Tabassum. I completed my B.Tech under CSE major. I'm currently learning React and recently, I have started 50 Projects 50 Days challenge. If you have any queries/ ideas to collaborate with me, you can connect with me at my social media handles.
Coming to our Drag N Drop Project, Let's Go!!
Glimpse of the output of our project:
From the above image, we can get an idea that there are some boxes. Out of these boxes, one box have an image. We can drag the image and drop in any of the boxes.
Tech stack we are using: HTML,CSS, JS
📌HTML code:
<body>
<div class="empty">
<div class="fill" draggable="true"></div>
</div>
<div class="empty"></div>
<div class="empty"></div>
<div class="empty"></div>
<div class="empty"></div>
</body>
Detailed Explanation of HTML code:
- According to the output, we need atleast 4-5 boxes. So we create 4-5 tags with an empty class inside it.
- For a image in the box, we create another inside the empty tag. And add an attribute draggable="true".
- draggable="true": The draggable attribute specifies whether an element is draggable or not.
📌CSS code:
@import url("https://fonts.googleapis.com/css2?
family=Roboto:wght@400;700&display=swap");
* {
box-sizing: border-box;
}
body {
font-family: "Roboto", sans-serif;
display: flex;
align-items: center;
justify-content: center;
overflow: hidden;
margin: 0;
height: 100vh;
}
.empty {
height: 150px;
width: 150px;
margin: 10px;
border: solid 3px black;
background: white;
}
.fill {
background-image:
url("https://source.unsplash.com/random/150x150");
width: 145px;
height: 145px;
}
.hold {
border: 3px solid red;
}
.hovered {
background-color: black;
border-color: rgb(32, 230, 32);
border-style: dashed;
}
@media (max-width: 480px) {
body {
flex-direction: column;
}
}
Detailed explanation of CSS code:
- For Centering of elements: Add properties like,
- display:flex - To lay a collection of items out in one direction or another.
- align-items:center - Centering the items.
- justify-content:center - Aligns the flexible container's items to center.
- height:100vh - The page's overall height
- overflow: hidden - This property makes the page unscrollable.
- For styling the empty class:
- Specify height and width of the box.
- Add background-color and border properties.
- For styling the fill class:
- Add background-image and height, width properties for the image.
- Add styling to hold class and hovered class which will be created further in JS.
- hold class styling - To create an effect around the image, when the image is dragged from the box.
- hovered class styling - To create an effect when the image is hovering on other boxes.
- Atlast, Add some responsive media queries 😊
📌JS code:
const fill = document.querySelector(".fill");
const empties = document.querySelectorAll(".empty");
fill.addEventListener("dragstart", dragStart);
fill.addEventListener("dragend", dragEnd);
empties.forEach((empty) => {
empty.addEventListener("dragover", dragOver);
empty.addEventListener("dragenter", dragEnter);
empty.addEventListener("dragleave", dragLeave);
empty.addEventListener("drop", dragDrop);
});
function dragStart() {
this.className += " hold"; //append the hold class here
setTimeout(() => (this.className = "invisible"), 0);
}
function dragEnd() {
this.className = "fill";
}
function dragOver(e) {
e.preventDefault();
}
function dragEnter(e) {
e.preventDefault();
this.className += " hovered"; //append hovered class
here while entering into the box.
}
function dragLeave() {
this.className = "empty";
}
function dragDrop() {
this.className = "empty";
this.append(fill);
}
Detailed explanation of JS code:
- Firstly, create the variables on which we are making DOM changes.
- On Fill box, we have two functions dragStart and dragEnd
- On Empty box, we have dragOver, dragEnter, dragLeave, drop functions.
- These functions are helpful in giving you an idea on drag and drop operations.
- We have to append the respective classes i.e., empty, fill classes while performing drag and drop on respective boxes.
Finally, the Live demo of output will be:

Today's Pinch of Motivation:
When you're high on emotion
And you're losing your focus
And you feel too exhausted to pray
Don't get lost in the moment
Or give up when you're closest
All you need is somebody to say
It's okay not to be okay
It's okay not to be okay
When you're down and you feel ashamed
IT'S OK NOT TO BE OK!!
