The order in your code is not correct. You must get an element after it is added to DOM.

Try the snippet.

const main = document.querySelector('.main-container')

let counter = 0 

main.addEventListener('click', e => {
  if(e.target.classList.contains('nextBtn')){
    counter++
    html=`
    <h1 class="text-uppercase">counter</h1>
    <h1 id="counter"class =count">${counter}</h1>
    <div class="btn-container d-flex justify-content-around flex-wrap">
    <button class="btn counterBtn prevBtn text-uppercase m-2">lower count</button>
    <button class="btn counterBtn nextBtn text-uppercase m-2">add count</button>
    `;
    main.innerHTML = html

  }else if(e.target.classList.contains('prevBtn')) {
    counter--
    html=`
    <h1 class="text-uppercase">counter</h1>
    <h1 id="counter">${counter}</h1>
    <div class="btn-container d-flex justify-content-around flex-wrap">
    <button class="btn counterBtn prevBtn text-uppercase m-2">lower count</button>
    <button class="btn counterBtn nextBtn text-uppercase m-2">add count</button>
    `;
    main.innerHTML = html
  }
  
  const button1 = document.querySelector('.prevBtn');
  const button2 = document.querySelector('.nextBtn');
  const count = document.getElementById('counter')

  if(counter > 0){
    count.style.color = 'green'
  } else if(counter < 0) {
    count.style.color = 'red'
  }
});
.main-container {
width: 100%;
height: 500px;
}
<div class="main-container nextBtn">Click On Me</div>
