Why are these input and text parts on the right side, if they supposed to be on the center?-CodePudding

I have a problem whit my new project. A login system. I did it from a youtube video:

The YouTuber's Log in system:

My code is also here:

.box {
  top: 80px;
  justify-content: center;
  align-items: center;
  position: relative;
  width: 380px;
  height: 420px;
  background: #000000;
  border-radius: 8px;
  overflow: hidden;
}

.box::before {
  content: '';

  top: -50%;

CodePudding user response：

To center those inputs you may add a margin-left and a margin-right of auto to .inputBox. Or simply change this:

.inputBox {
  position: relative;
  width: 300px;
  margin-top: 35px; /** change this */
}

into this:

.inputBox {
  position: relative;
  width: 300px;
  margin: 35px auto 0; /** into that */
  /** 
  * the above rule means:
  *   - 35px as margin top
  *   - left and right margins set to "auto" which horizontally centers your ".inputBox"
  *   - 0px as margin bottom
  */
}

And here's a live demo (made some changes to your code because you had some tags that were not closed)

.box {
  top: 80px;
  justify-content: center;
  align-items: center;
  position: relative;
  width: 380px;
  height: 420px;
  background: #000000;
  border-radius: 8px;
  overflow: hidden;
}

.box::before {
  content: '';
  position: absolute;
  top: -50%;
  left: -50%;
  width: 380px;
  height: 420px;
  background: linear-gradient(0deg, transparent, #00d8d6, #00d8d6);
  transform-origin: bottom right;
  animation: animate 6s linear infinite;
}

.box::after {
  content: '';
  position: absolute;
  top: -50%;
  left: -50%;
  width: 380px;
  height: 420px;
  background: linear-gradient(0deg, transparent, #00d8d6, #00d8d6);

CodePudding user response：

Compared to the video, you are missing a padding: 50px 40px; in the .form part.

Try replacing your .form css with this:

.form {
    position: absolute;
    inset: 3px;
    border-radius: 8px;
    background: #343745;
    z-index: 10;
    padding: 50px 40px;
    display: flex;
    flex-direction: column;
}

UPDATE: furthermore, there is an issue with the <h4> tag which is opened twice. Maybe you should have <h4>Log In</h4>.
