HTML & CSS Can someone help me find the error in my code?

[tae20]

My content won't rest inside my background image properly. I need it to be centered with one another. It's just not happening.

}

@media (min-aspect-ratio: 16/9) {
   .back-video {
    width: 100%;
    height: auto;
   }
}

@media (max-aspect-ratio: 16/9) {
    .back-video {
     width: auto;
     height: 100%;
    }
 }

I tried changing the position and display of the hero class but it did nothing.

Hey there! It looks like your main issue is that the text and button aren’t actually sitting on top of your video background; instead, they’re placed in a whole separate section (section class="content"). Since your .hero section is the one with the video background (and the flex centering styles), the easiest fix is to move your heading and button inside that same .hero container.

Here’s how you might restructure your HTML:

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
    <title>Background Video</title>
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <section class="hero">
      <video autoplay loop muted playsinline class="back-video">
        <source src="assets/4763824-uhd_3840_2160_24fps.mp4" />
      </video>
      <!-- Move your content here so it overlays the video -->
      <div class="content">
        <h1>Journey</h1>
        <a href="#">Explore</a>
      </div>
    </section>
  </body>
</html>

Then, in your CSS, make sure the video is behind everything else and the content is centered:

.hero {
  position: relative;
  width: 100%;
  height: 100vh;
  background-image: linear-gradient(rgba(12, 3, 51, 0.3), rgba(12, 3, 51, 0.3));
  display: flex;
  justify-content: center; /* centers horizontally */
  align-items: center;    /* centers vertically */
  overflow: hidden;       /* hides any overflow from the video */
}


.back-video {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  object-fit: cover;  /* ensures the video covers entire section */
  z-index: -1;        /* sends the video behind the content */
}


.content {
  text-align: center;
  z-index: 1;         /* ensures the text is above the video */
}


.content h1 {
  font-size: 160px;
  color: #fff;
  font-weight: 600;
  transition: 0.5s;
}


.content h1:hover {
  -webkit-text-stroke: 2px white;
  color: transparent;
}


.content a {
  text-decoration: none;
  display: inline-block;
  color: #fff;
  font-size: 24px;
  border: 2px solid white;
  padding: 14px 50px;
  margin-top: 20px;
  transition: 0.5s;
}


.content a:hover {
  background: #fff;
  color: #000;
}

With these tweaks, your heading and button should be nicely centered over the video background, matching your expectation screenshot. Hope that helps!
