Here is the solution of mine
<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
font-family: Lobster, Monospace;
border:10px solid green;
<img class="smaller-image thick-green-border" src="https://bit.ly/fcc-relaxing-cat" alt="A cute orange cat lying on its back. ">
<p class="red-text">Kitty ipsum dolor sit amet, shed everywhere shed everywhere stretching attack your ankles chase the red dot, hairball run catnip eat the grass sniff.</p>
<p class="red-text">Purr jump eat the grass rip the couch scratched sunbathe, shed everywhere rip the couch sleep in the sink fluffy fur catnip scratched.</p>
add class named thick-green-border to your img tag and declare a class named .thick-green-border in under the style tag. and add border properties.
