Problem of Task

I don't understand the task : "Finally, let's reduce the width of the main-content div. Give it a width value that takes up 75 percent of its container's width."

I make : .main-content { width : 100%; }

and the task say "bummer", i don't understand... Sorry for my bad english !

/* Complete the challenge by writing CSS below */
.title  {
  font-size : 26px;

h2 {
  font-size : 53px;

.container {
  width : 100%

.main-content {
  width : 75%;
<!DOCTYPE html>
    <title>Lake Tahoe</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
    <div class="container">
        <span class="title">Journey through the Sierra Nevada Mountains</span>
        <h1>Lake Tahoe, California</h1>
      <div class="main-content">
          Lake Tahoe is one of the most breathtaking attractions located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.

          As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.

The challenge may be a bit picky about spacing.

I see that it let it by in the earlier tasks, but for task 3 I don't think the challenge likes the space between "width" and the colon ":".

You might want to report this behavior as a bug using the Support page.
