How to add Text Resizer functionality in blogger?

Before we start adding codes in XML, I will recommend you to take a Backup of your current theme. By chance if any problem occurs, you can restore it later.

Step 1: Go to Blogger Dashboard.

Step 2: On Blogger Dashboard, click Theme. 

Step 3: Click the arrow down icon next to 'Customize' button. 

Step 4: Now click on Edit HTML 

Step 5: Now search the code </body> Paste the following Codes just above to it.

<b:if cond='data:view.isPost'>

  <div class='textResizer'>

    <div id='increaseFont'>A+</div>
    <div id='decreaseFont'>A-</div>

  </div>

</b:if>

<style>

  /* Text Resizer CSS */
  .textResizer {
    position: fixed;
    right: 25px;
    bottom: 150px;
    background: #ffffff;
    box-shadow: 0 0 5px #000000;
    border-radius: 5px;
    box-sizing: border-box;
    z-index: 1;
    transition: all .3s linear;
  }

  .darkMode .textResizer {
    background: var(--darkU);
    color: #ffffff;
    box-shadow: 0 0 5px #ffffff;
  }

  #increaseFont, #decreaseFont {
    font-size: 18px;
    padding: 10px;
    box-sizing: border-box;
    background: #ffffff;
    color: #000000;
  }

  .darkMode #increaseFont, .darkMode #decreaseFont {
    background: var(--themeC);
    color: #ffffff;
    border-color: #ffffff;
  } 

  #increaseFont {
    border-radius: 5px 5px 0 0;
    border-bottom: .5px solid #000000;
  } 

  #decreaseFont {
    border-top: .5px solid #000000;
    border-radius: 0 0 5px 5px;
  } 

  #increaseFont:hover, #decreaseFont:hover {
    background: var(--themeC);
    color: #ffffff;
  }

</style>

<!-- Load jQuery -->
<script src='https://code.jquery.com/jquery-3.6.0.min.js'/>

<script>
  /*<![CDATA[*/ 
  $(document).ready(function() {
    // Increase font size
    $("#increaseFont").click(function() {
      let curSize = parseInt($(".postBody").css("font-size")) + 1;
      if (curSize <= 20) {
        $(".postBody").css("font-size", curSize);
      }
    });

    // Decrease font size
    $("#decreaseFont").click(function() {
      let curSize = parseInt($(".postBody").css("font-size")) - 1;
      if (curSize >= 10) {
        $(".postBody").css("font-size", curSize);
      }
    });
  });
  /*]]>*/ 
</script>

Step 10: Then Save the HTML.
