I don't know how to add these features to the site-CodePudding

I need to add 3 buttons to my header 1 - a search bar 2 simple button in the form of text Enter and 3 is a picture of a bag with the number 0

yes i know for a pro in html the question will sound stupid but i am newbie and i need to add this to my header in its free part,I have never made this type of button in the header and you will probably find a lot of mistakes in my code.

yes, I know what you will say "there is no one here who will not write the code for you", but I have never hidden even with the search bar, and I have also never made a login button with an icon in front of it, and I lack the experience to do it

my site code - html :

<!DOCTYPE html>
<html lang="en">
<head>
  <header >
  <a href="" >Fresh market</a>
  <input  type="checkbox" id="menu-btn" />
  <link rel="stylesheet" href="style.css">
  <label  for="menu-btn"><span ></span></label>
  <ul >
    <li><a href="#work">Home</a></li>
    <li><a href="#about">Shop</a></li>
    <li><a href="#careers">About</a></li>
    <li><a href="#contact">Contact</a></li>
  </ul>
</header>
