Tips for creating dynamic images in a flexible design

When creating a fluid layout, you can use em or % for font and div width and height to achieve fluidity. However, the challenge lies in making images resizable.

I aim to design a single layout that works seamlessly across all screen sizes and devices.

Joel Spolsky was able to discover a simple solution (using a unique CSS definition for IE). The solution can be found here.

Answer №2

Finding a solution to this issue is complex. Utilizing flexible units for images, similar to how you approach other elements on your webpage, is an option. However, this approach may lead to inefficiencies and visual challenges such as increased file size for smaller images (when resized) and pixelation for larger images. The optimal strategy would involve starting with a larger image and then scaling it down to create various size versions. Additionally, employing Javascript to dynamically select the appropriate sized image based on the context can be beneficial.

Answer №3

While it is possible to size images relative to the viewport width using CSS (for example, img.thing { width: 50%; }), it is generally not recommended. This is because scaled images can appear blurry or blocky/jaggy depending on the resizing algorithm used by the browser. Although there are some CSS properties like SVG's image-rendering and -ms-interpolation-mode in IE that attempt to improve image quality during scaling, they are not always reliable.

Furthermore, CSS background-images cannot currently be resized at all, although this feature is being proposed for CSS3.

In a liquid layout design, the goal is to adjust the spacing between fixed-size images based on changes in viewport width rather than resizing the entire page, including images. Users can still zoom in on the page with modern browsers, but may experience a decrease in image quality as a result.

Answer №4

To achieve this, I suggest utilizing the canvas element in HTML5. Alternatively, you could utilize JavaScript to dynamically set the size of the image element, although it may require some mathematical calculations to ensure correct proportions.
