i have set a max-width of 100% to the li elements inside of #gallery, but it does not apply it to images.

I cannot see the html to see what i would apply a max width to in order to set it for the images.

#gallery li {
  max-width: 100%

a {
  text-decoration: none;

#wrapper {
  max-width: 940px;
  margin: 0 auto;

#logo {
  text-align: center;
  margin: 0;

h1, h2 {
  color: #fff;

nav a {
  color: #fff;

nav a:hover {
  color: #32673f;

h1 {
  font-family: Changa One, sans-serif;
  font-size: 1.75em;
  font-weight: normal;

Or if there are multiple images, you could also use

gallery ul {

max-width: 100%; }

if you use li, you only target a single list item so use the unordered list to select all of the list items that are in the gallery, another theory is that the gallery is a class in which it could be .gallery instead of #gallery.

You can target the image like this

#gallery img {
  max-width: 100%;
