How Can I Center a Div Element on the Screen Using Only CSS?

Centering a

Element on Screen with CSS

When creating web layouts, it's often necessary to position elements at the center of the screen. This can be achieved using CSS, eliminating the need for inline styles or complex JavaScript solutions.

Fixing the Element's Width and Height

One straightforward approach is to define a fixed width and height for the

element:

#divElement {
    width: 100px;
    height: 100px;
}

Copy after login

Positioning the Element

To position the element at the exact center, we use absolute positioning:

#divElement {
    position: absolute;
}

Copy after login

Calculating Center Coordinates

To determine the center of the screen, we need to find the midpoint of its width and height. This involves dividing them by two:

top_margin = screen_height / 2;
left_margin = screen_width / 2;

Adjusting the Element's Margins

To adjust the element's position, we use negative margins. This moves the element half its height and width from its original position, centering it on the screen:

#divElement {
    margin-top: -top_margin;
    margin-left: -left_margin;
}

Copy after login

Complete Example

Putting it all together, here's the complete CSS code:

#divElement {
    position: absolute;
    top: 50%;
    left: 50%;
    margin-top: -50px;
    margin-left: -50px;
    width: 100px;
    height: 100px;
}
