How can I align center css to DIV?

To align the contents of a <div> horizontally and vertically, you can use CSS flexbox or text-align property. Here's how you can do it with each method:

Using Flexbox:.center-div {
  display: flex;
  justify-content: center; /* Horizontal alignment */
  align-items: center; /* Vertical alignment */
}
Using text-align (for inline or inline-block elements within the div):

.center-div {
  text-align: center; /* Horizontal alignment */
}
 

Certainly! To center the <h1> element inside the “inner” <div> horizontally, you can use the following CSS techniques:

1. Using margin: auto;:

   • Apply margin: auto; to the “inner” <div>. This will horizontally center the entire div within its parent container.
   • Example:

     CSS  #inner {
       margin: auto;
       width: 50%; /* Set an appropriate width for the inner div */
     }

2. Using text-align: center;:

   If you want to center only the text inside the <h1> element, apply text-align: center; directly to the “inner” <div>.
   Example:
   CSS  #inner {
     text-align: center;
   }

3. Combining both methods (centering both the div and its content):

   Apply margin: auto; to the “inner” <div> for horizontal centering.
   Use text-align: center; to center the text inside the <h1> element.
   Example:
   CSS   #inner {
     margin: auto;
     width: 50%; /* Set an appropriate width for the inner div */
     text-align: center;
   }
   
   Remember to adjust the width and other styles according to your design requirements. The above examples assume that the “inner” <div> has a specified width.

To align the `<h1>` element to the center of the page using CSS, you can apply the following styles:

css
#outer {
  display: flex;
  justify-content: center;
  align-items: center;
  height: 100vh;
}

#inner {
  text-align: center;
}.
