Though there are different types of “About Me” widgets available using which you can create “About Me” box, the easiest and simplest way is to create your own “About Me” is using HTML widgets on the sidebar or the footer or basically anywhere you want.
Use the below code and replace it with your own text and add it as an Custom HTML widget in the sidebar
<div>
<p style='display:block;text-align:center;float:center;'>
<img src="https://www.yoursite.com/wp-content/uploads/2023/09/Shan100.jpeg" alt="Shan" style='width:100px !important;'>
<h3 style='text-align:center;font-family:Faustina;color:#000000;font-size:20px;'>Shan</h3>

In the above code snippet, the image links to your profile image. You can upload an image into WordPress media, then copy the link from the uploaded image and paste it over here.
The content within the span tag can be edited as you like. I have put in my text from one of my websites on the OceanWP theme and the same can be used in any theme without editing the content a lot. (You can also add images to the social links and have your own social links icon also)
