Trouble with applying multiple CSS classes

I’ve been trying to pass the lesson Basic CSS: Add Borders Around Your Elements. I can only get one or the other class smaller-image or thick-green-border to apply. I used spaces between the two classes and switched from safari to chrome with no luck on getting both to apply.
my code is

.smaller-image {
    width: 100px;

  .thick-green-border {
    border-color: green;
    border-width: 10px;
    border-style: solid;
<a href="#"><img class="thick-green-border" "smaller-image" src="" alt="A cute orange cat lying on its back."></a>

what am I doing incorrectly ?

Hi @RedSun,
When you add multiple classes to an element, you don’t need to put " " around each of the classes.
For example,
<h1 class="large red"> instead of <h1 class="large" "red">
Hope that helps.

What a simple mistake I made. Thank You for the help

My pleasure! It always seems like the simple things to me too when I get caught up on a question. :slight_smile:
