There are several methods to center a div within its parent div in HTML and CSS. Here are some common methods:

1. 1. Using Flexbox:

   css
   .parent {
       display: flex;
       justify-content: center; /* Horizontally center */
       align-items: center; /* Vertically center */
   }
   

2. 2. Using Grid:

   css
   .parent {
       display: grid;
       place-items: center;
   }
   

3. 3. Using Absolute Positioning:

   csscode
   .parent {
       position: relative;
   }
   .child {
       position: absolute;
       top: 50%;
       left: 50%;
       transform: translate(-50%, -50%);
   }
   

4. 4. Using Grid with Flexbox Fallback (for older browser support):

5. css
   .parent {
       display: grid;
   }
   .child {
       justify-self: center;
       align-self: center;
       display: flex;
   }
   

Each of these methods has its advantages and may be more suitable depending on the specific layout requirements and browser support considerations of your project. Flexbox and Grid are the most commonly used methods due to their flexibility and ease of use for complex layouts.
