Pure CSS Image Loader

Add a image loader & image load error (without adding an HTML element or using JS). Just pure CSS!

Show your support!

Note: this is just a proof of concept. You should still provide a fallback source for your images using an onerror etc. As iOS / Webkit devices do NOT currently support the CSS attribute ::before needed for the fallback error image.

    Improve responsive behavior

    Here you have a demo with a closer structure as you used for your code:

    In this case you don't need to know the height and the width of the image (in CSS), but is always recommended to put the size in your <img> tag.

      <source media="(min-width:650px)" srcset="img_pink_flowers.jpg">
      <source media="(min-width:465px)" srcset="img_white_flower.jpg">
      <img src="img_orange_flowers.jpg" alt="Flowers" style="width:auto;">

    Do you think it's necessary to specify in this project?

    fixed sizes, removed overflow and commented better

    • I fixed the image sizes together with the error image with the object-fit property
    • Removed the horizontal overflow which was caused due to having larger image
    • Added more reset rules
    • Left content url as it is for the case of base64 image
    • Gave the layout better fonts.
