[SOLVED] @keyframes not working in expected way CSS

I'm recoding this website for practice purposes. I've changed the background image to black in my codepen because images don't work in codepen. Here's a link to my code. I've also placed the code here in case you can't view the codepen:


<!DOCTYPE html>
<html lang="en">
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <link rel="stylesheet" type="text/css" href="">
  <link rel="stylesheet" type="text/css" href="">
  <link href="" rel="stylesheet">
  <title>Coming Soon</title>
  <div class="background">
      <h2 class="logo">Logo</h2>
      <div class="dropdownwrapper">
        <h1 class="bigtext">Coming Soon</h1>
      <hr class="divider">
      <h4 class="smalltext">35 days left</h4>


  body {
  background-color: white;
  font-size: 10px;

.background {
  animation-name: fadeout;
  animation-duration: .8s;
  background-image: url(Images/forestbridge.jpg);
  background-size: cover;
  background-position: top;
  animation-fill-mode: backwards;
  height: 100vh;
  font-family: "Raleway", sans-serif;

.logo {
  color: white;
  font-weight: 100;
  font-size: 1.5rem;
  padding: 1rem 0 0 1rem;

.bigtext {
  color: white;
  text-transform: uppercase;
  font-size: 4rem;
  text-align: center;
  padding-bottom: 1rem;

.dropdownwrapper {
  animation-name: dropdown;
  animation-duration: .8s;
  animation-fill-mode: forwards;

.divider {
  border: none;
  width: 20%;
  height: 1px;
  background-color: lightgrey;
  margin-bottom: 1.5rem;

.smalltext {
  color: white;
  font-size: 1.25rem;
  text-align: center;

@keyframes fadeout {
  0% {
    opacity: 0;

  100% {
    opacity: 1;

@keyframes dropdown {
  0% {
    margin-top: 10vh;

  100% {
    margin-top: 40vh;

I also have a , but it's just a standard Eric Meyer 2.0 reset (I've placed it in the codepen, though). My problem is that when you reload the W3Schools version I'm attempting to recode, the text "COMING SOON" comes down, and the line and "35 days left" text stay in place. However, in my code, the entire block of text comes down. Why is the "COMING SOON" text on my site not coming down by itself when I've only selected it's parent div that the other elements are in? How can I make it so that only the "COMING SOON" text comes down?

This is happening because you are animating the margin-top of the COMING SOON text. Since the element is in the normal document flow, animating the margin gives the impression that the elements after the COMING SOON are also being animated, even though they are not. To resolve this, you should be animating using transform, which manipulates an element's position in place. Check out the forked codepen.

Additionally, if you wish to centre the entire block of text in the centre of the page, you should wrap all of it an div and position it absolutely. I've forked another codepen to demonstrate this.

The slide down effect appears more profound in the second codepen.

Trying to Delete an object using shell in django. How do i delete the object say "Ron"?I use the following command:t.delete('Ron') The error: object can't be deleted because its id attribute is set to NoneSuggests that you either never saved the object t in the first place, or you changed the primary key (here id) to None manually.If you have a single object you can perform a .delete() on the object, for example:my_obj = Model.objects.get(name='Ron')my_obj.delete()You should not add extra parameters to delete except for using and keep_parents, as specified in the docume...
