Tips for positioning a Div element in the center of a page with a full-page background

I am trying to center align my div containing login information on the webpage. The static values seem to work fine, but I am looking for a way to position it dynamically. Additionally, the background is only covering a strip with the height of the div...

Below is the code snippet:

.bold{
font-weight: bold
}

#login {
width: 300px;
margin-left: auto;
    margin-right: auto;
    margin-top: 15%;
    background-color: white;
    border-style: outset; <!--Just there to show the border-->

}

.background {
background-color: #f5f5f0;
min-height: 100%;
height: auto !important;
}

<div class=background>
<div class="well well-lg" id="login">
<h2>LOGIN</h2>
<form method="post" ng-submit="login()">
<input name="username" type="text" ng-model="username" placeholder="username"><br>
<input name="password" type="password" ng-model="password" placeholder="password"><br>
<input type="submit" value="Einloggen">
</form>

</div>

  top: 50%;
  left: 0;
  right: 0;
  margin: auto;
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  transform: translateY(-50%);
}

For maximizing the background:

.background {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 100%;
  background-color: #f5f5f0;
}

Answer №6

Here is a solution that may fit your needs. Instead of setting the background for a div, try applying it to the body tag. Then, include display: inline-block; in the styling of #login. Additionally, center align the content within .background to ensure the login form appears at the center.

.bold {
  font-weight: bold
}
#login {
  
  background-color: white;
  border-style: outset;
  margin: auto;
  margin-top: 15%;
  text-align: center;
  display: inline-block;
}
.background {
  background-color: #f5f5f0;
  height: 100%;
  width: 100%;
  text-align: center;
}

<body class="background">
  <div>
    <div class="well well-lg" id="login">
      <h2>LOGIN</h2>
      <form method="post" ng-submit="login()">
        <input name="username" type="text" ng-model="username" placeholder="username">
        <br>
        <input name="password" type="password" ng-model="password" placeholder="password">

Answer №8

Start by eliminating the background div and allowing the background color to be on the body (or html). You can position the #login element as absolute (affected by scroll) or fixed (ignores scroll). Calculate the top/left position of #login by subtracting half the object width from the page width and half the object height from the page height.

body {
  height: 100%;
  width: 100%;
  margin: 0px;
  background-color: skyblue;
  font-family: arial, sans-serif;
}

#login {
  height: 130px;
  width: 300px;  
  background-color: gold;
  outline: 2px solid black;  
  position: fixed; /* or absolute */
  top: calc(50% - 65px);
  left: calc(50% - 150px);
}

input {
  padding-left: 2px;
  padding-right: 2px;
  margin-left: 15px;
  margin-bottom: 2px;
  border: 2px solid black;  
}

input:focus {
  outline: 0;
  background: tomato;
}

::-webkit-input-placeholder {
  color: black;
}

::-moz-placeholder {
  color: black;
}

h2 {
  margin-left: 5px;
  margin-top: 5px;
  margin-bottom: 5px;
}

<div class="well well-lg" id="login">
<h2>LOGIN</h2>
<form method="post" ng-submit="login()">
<input name="username" type="text" ng-model="username" placeholder="Username"><br>
<input name="password" type="password" ng-model="password" placeholder="Password">
<br>
<input type="submit" value="Einloggen">
