Images in the course

  • Content blocks can accommodate images of various sizes, and no specific width can be set for them.
  • Use images where the key content is centred within the image.
  • Check that the images display correctly when you resize the screen.

Event block image

  • Prefer square-shaped images.
  • The same image is also used as the event’s representative image in event listings.

Note

  • Use images of the highest possible quality to ensure they appear sharp on different screen sizes.
  • Position important elements in the centre of the image so that they are not cropped out on different devices.
  • Test the images on both computers and mobile devices.
  • Always add alt text to images whenever an image contains information that is essential to the user.
