Hey Louis,

Try this:

@media (min-width: 607px) {
    img {
        float: left;

did you see how I copied my code... I was gettin frustrated lol

That's understandable. Just remember when writing media queries that you'll need an opening and closing curly bracket when targeting an element.

Here are a few examples:

@media (min-width: 607px) {
    p {
        font-size: 0.95em;
    h1 {
        color: red;
    .exampleClass {
        padding: 10% 5%;
    #exampleID {
        margin-bottom: 2%;

thanks. do you know what video I can refer back to bay chance?
