Placing an image to the top right corner - CSS

The theory: Positioning and responsiveness

To make your design adaptive across device screens, introduce media queries in your CSS. This adjusts the image's position or size on different screens, providing a seamless user experience.

Since we use position: absolute; for the image, it is lifted out of the standard document flow. This means it won't disrupt the placement of sibling elements contained within the same parent, assuring layering of elements.

@media screen and (max-width: 768px) {
  img.ribbon {
    width: 50px; /* Smaller image size on mobile devices to keep the things tidy */
    height: auto;
  }
}


To easily manipulate an image, assign a class="ribbon" to it. This gives you control to style or resize it according to your needs.

Getting fancy: Image loading and accessibility

You might want to use PNG or GIF file formats with transparent backgrounds. This adds a layer of polish if the image is a decorative element. Explicitly define the height and width attributes to preserve the image's aspect ratio and prevent layout shift during loading.

A nifty way to load your image and exercise additional control involves using the background property in CSS:

.ribbon {
  background: url('image.jpg') no-repeat top right;
  height: 100px;
  width: 100px;
}


Ensure accessibility by providing a meaningful alt attribute for your image. This will aid screen reader users. Further enhance the image by adding a CSS border to make it stand out.

Beyond positioning: getting strategic

Structure and cleanliness

Maintaining a clean HTML structure eases readability and management. It's always a good practice to logically group your elements, and remember to use the <style> and <pre><code> tags to format your CSS and HTML code examples.

Responsive designs

Flexbox, a modern layout mode in CSS, is an excellent method for more complex designs. It aligns items in a container gracefully, even when their dimensions are dynamic and varying.

Advanced enhancement techniques

For extra flair, consider using pseudo-elements like ::before or ::after. You can absolutely position these elements within a relatively positioned parent, similar to images.
