Ways to magnify a specific class or id in css3 when hovered over

Currently, I am in the process of learning CSS3 but struggling with implementing classes in CSS3. Can someone offer their assistance?

<!DOCTYPE html>
<html>
<head>
    <title>Zoom Hover</title>
        <style type="text/css">

    @-moz-keyframes 'zoom' {
        0%{
            height:200px;
            width:200px;
            }
        100% {
                width: 1000px;
                height: 1000px;
            }
    }

    @-webkit-keyframes 'zoom' {
        0%{
            height:200px;
            width:200px;
            }
        100% {
                width: 1000px;
                height: 1000px;
            }
    }    

.aaa{
    width:200px;
    height:auto;

    }

.aaa:hover {
    -moz-animation-name: 'zoom' 2s;
}
.aaa:hover {
    -webkit-animation: 'zoom' 2s;
}
.aaa{
    width:200px;
    height:200px;
    -moz-transition-duration: 2s; /* firefox */
    -webkit-transition-duration: 2s; /* chrome, safari */
    -o-transition-duration: 2s; /* opera */
    -ms-transition-duration: 2s; /* ie 9 */
}
.aaa:hover {
    width: 1000px;
    height: 1000px;
}
    </style>
</head>
<body>

<div class="aaa"style="width:100px;height:100px;background:red;"></div>
</body>
</html> 

I'm seeking guidance on the best way to approach this, so please assist me. Also, does anyone know a reliable website where I can learn more about CSS3?

Answer №1

To effectively "zoom in" on an element using CSS, utilize a transformation and scale it to the desired size:

transform: scale(2);

This action will enlarge the element and all of its contained content by a factor of 2.

For a comprehensive example, consider the following:

CSS

.example {
    width: 100px;
    height: 100px;

    -webkit-transition: all 2s ease-in-out;
    -moz-transition: all 2s ease-in-out;    
    -ms-transition: all 2s ease-in-out;
    -o-transition: all 2s ease-in-out;    
    transition: all 2s ease-in-out;
}

.example:hover {
    -webkit-transform: scale(2);
    -moz-transform: scale(2);
    -ms-transform: scale(2);
    -o-transform: scale(2);
    transform: scale(2);
}

Live Demo

Experience before committing (using transform and scale)

Your initial attempt focused on altering the dimensions of the element rather than truly zooming in. This method creates a larger appearance without affecting child elements. To achieve this effect more efficiently, consider utilizing transitions instead of animations:

CSS

.example:hover {
    width: 200px;
    height: 200px;
}
