Code Explanation for Responsive Image

In creating responsive images, the first thing to consider is that the image needs to fit its containing element. We achieve this fit through the properties max-width and height, which we properly define in our CSS code snippet above.

Let’s break down what each line of the code does:

1. img: This CSS selector is specifically targeting all images on your webpage. All styles within this selector will be applied to these images.

2. max-width: 100%;: The max-width property allows the width of the image to be a maximum of 100% of its containing element. Therefore, the image will never be wider than its container. This is particularly useful when viewing the site on smaller screens, as the image will automatically adjust itself to the width of the device.

3. height: auto;: The height: auto; CSS property setting ensures that the aspect ratio of the image remains the same as the image shrinks or expands. It means that when max-width of the image is reached, the height automatically adjusts to maintain the aspect ratio.

There you have it. With just a few lines of CSS, you can make your website images responsive to different devices, contributing to a better, more enjoyable browsing experience for your visitors.
