Start by creating a class an applying it to the element. Re-read the instructions again carefully. They tell you what properties you need to assign in order to control the image.
Creating the element is possible in two ways if my understanding is correct; the better one being However, is the location within the code important? I’m not sure where to create class.
You have probably created a CSS entry in the lessons before: so create a class in the CSS style with .smaller-image { }
Your computer is very smart, but needs some help here, because it does not know what you want to make smaller, therefore you need to add the class to one of the tags. You can guess it, but its probably the img tag. This you have done before too in the lessons.
So if you do these two steps you will get the right result + your browser needs to be at 100%.
=) Good Luck!
Also if you need any help in the future, try to dissect what is asked first and to look up things on the web as well, there are great sources out there which explain exactly how to add a class in CSS and HTML. For me it really helped to learn this order: 1. First read what is asked, 2. Make some steps for yourself, 3. if you do not get one step, search for it online, 4. if you do not find any answers for your searches, then ask on a forum. Then you teach yourself to first look and understand, recap what you learnt and then ask people for hints or even the answer. Not that you should not ask questions on forums! That is super helpful too! Happy Coding!
