Something is wrong

I’m trying to build my portfolio using HTML,CSS and JavaScript. As much I know the codes are all correct but I really not able to figure out why the changes in the webpage are not correct as per the code. Can you suggest me the changes?

here is my code: (HTML)

`

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta charset="utf-8">
    <title>Sagnik Saha </title>
    <link rel="stylesheet" href="styles.css">
  </head>
  <body>
<div class="toggle" onclick="toggleMenu();">

</div>

<section class='banner' id="home">

  <div class="imgSidebar">
    <img src="me.jpg" alt="">

  </div>
<div class="contentBx">
  <h5 class="logoText">My Protfolio</h5>
  <div class="">
    <h4><span>Hello </span>, I'm</h4>
    <h2>Sagnik Saha</h2>
    <h4>I'm a programmer</h4>
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

I’m still trying the texts to be on the right hand side of the page and not to get overlapped with the picture.
