Can someone explain me what I did wrong? On the upper side of each picture there is a dot.

Hi Rein, I'm guessing the dots you see are the bullet points from using a list item tag around the image.

I downloaded Nick's demo files and see a dot at the bottom left of the image in Safari. The appearance can vary depending on which browser you use as they all have their own default styles for elements.

Good news, you didn't do anything wrong!

Why do they appear? List elements most basic usage is for a list

e.g.

• cat
• dog
• mouse

Lists are also useful for other things though, like in this case a list of images.

How to fix it? Later videos will cover how to remove these default styles. If you know how to add CSS you can use the following to remove it.

ul {
list-style: none;
}
