How to Make Images Automatically Resize with Browser Window Using CSS?

Automatically Resize Images Using CSS Browser Size

Problem:

Your images do not automatically resize when you resize your browser window. You have tried the following code but it does not work:

HTML:

<code class="html">

    
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1.0">
        <link rel="stylesheet" href="style.css" type="text/css" media="screen">
    
    
        <div id="icons">
            <div id="contact">
                <img src="/static/imghwm/default1.png" data-src="img/icon_contact.png" class="lazy" alt="">
            </div>
            <img src="/static/imghwm/default1.png" data-src="img/icon_links.png" class="lazy" alt="">
        </div>
    
</code>

CSS:

<code class="css">body {
    font-family: Arial;
    font-size: 11px;
    color: #ffffff;
    background: #202020 url(../../img/body_back.jpg) no-repeat top center fixed;
    background-size: cover;
}

#icons {
    position: absolute;
    bottom: 22%;
    right: 8%;
    width: 400px;
    height: 80px;
    z-index: 8;
    transform: rotate(-57deg); 
    -ms-transform: rotate(-57deg); 
    -webkit-transform: rotate(-57deg); 
    -moz-transform: rotate(-57deg);
}

#contact { 
    float: left; 
    cursor: pointer; 
}


img { 
    max-width: 100%; 
    height: auto; 
}</code>

Solution:

To make your images flexible, add the following CSS properties:

<code class="css">img {
    max-width: 100%;
    height: auto;
    width: auto; /* for IE8 compatibility */
}</code>

By setting max-width to 100%, the image will never exceed the width of its container. Setting height to auto allows the image to maintain its aspect ratio while resizing. The width: auto9 override is necessary for IE8 compatibility.

With these properties in place, any images you add using the img tag will be automatically resized to fit the size of your browser window.
