Using bootstrap's center-block class, you can easily center

I'm attempting to center the content of a form.

<div class="login-container">
 <div class="center-block">
    <form action="/joinChart" method="get">
        <input name="username" id="username" type="text"><br><br>
        <input type="submit" value="enter your name">
    </form>
  </div>
</div>

In my style.css file (for center-block)

.center-block {
display: block;
margin-left: auto;
margin-right: auto;
 }

.element {
   . center-block();
}

and for login-container:

  .login-container {
position: absolute;
width: calc(100% - 20px);
max-width: 800px;
height: 500px;
border-radius: 10px;
left: 50%;
top: 50%;
transform: translateX(-50%) translateY(-50%);
overflow: hidden;
}

Unfortunately, I am having trouble achieving this.

Answer №1

One way to achieve this is through the use of Flexbox. Here's a helpful resource:

.center-block {
  background-color: darkgrey;
  text-align: center;
}

.login-container {
background-color: lightgrey;
  display: flex;
  justify-content: center;
}
<div class="login-container">
  <div class="center-block">
    <form action="/joinChart" method="get">
      <input name="username" id="username" type="text"><br><br>
      <input type="submit" value="enter your name">
    </form>
  </div>
</div>

Answer №3

Each web browser has its unique CSS requirements. Your code should work fine on Google Chrome, Opera, and Microsoft Edge. However, if you're using Internet Explorer, make sure to add text-align : center; after the margins in your .center-block CSS selector.
