3rd question not working

// 3: Select all elements with the class '.card'. 
//    Set their background color to the color of your choice.
const myClass=document.getElementsByClassName('card');
for(let i=0;i<myClass.length;i++){
myClass[i].style.backgroundColor='pink';
}

Your code is accurate, but you selected an element not a class, to select a class you have to put a '.' in front of the class name.

For example

const myClass=document.getElementsByClassName('.card');
for(let i=0;i<myClass.length;i++){
myClass[i].style.backgroundColor='pink';
}

It should work with this fix.

I thought that you only had to add the '.' before a class name in a querySelector not in getElementsByClassName, as it's already obvious that you're looking for a class. Vijayalaxmi has just copied the teacher here.

Yes the example the instructor is using getElementsByClassName without the dot and his is rendering. mine is only rendering the first two. Also if I use the dot like you suggested it does not work at all.

I got it to work using document.querySelectorAll('.card'); Then use the for loop.
