As I already said in my comment, you can't do it without JavaScript.
A JavaScript solution would be the following:

const container = document.getElementById("container");

for (let i = 0; i < 200; i++) {
  const item = document.createElement("div");

  item.classList.add("item", "item-" + i);

  container.appendChild(item);
}

#container {
  border: 1px solid red;
  padding: .5rem;
}

.item {
  border: 1px solid black;
  height: 3rem;
  margin-bottom: .3rem;
}

<div id="container">
</div>

One way with js: you can create one HTML Span Element and with js you change the content of it. I bet with that knowledge you find something

how it's going? Html or css is not a programming language. So you can't do some kind of automation or repeating code or something like that. The only way to do that sort of things is using Javascript. Here is how:

<div class="container">
  <!-- let's say we trying to add divs here. -->
</div>

And here's script:

function addMultiple (where, what, count, callBack) {
  for (let i = 0; i < count; i++) {
    // creating elements with document.createElement() method
    let item = document.createElement(what)
    // and then adding them into "where" element.
    where.appendChild(item)
    
   /*
    and finally we'll have a function called Callback.
    This is just gonna take our item as an argument and 
    do some stuff on it according to what we want.
    (I'll show a simple usage down below)
    */
   callBack(item)
  }
}

// let's say we want to add 200 divs into "container" element 
// and then we want to add class name to those divs.

const container = document.querySelector('.container')
addMultiple(container, 'div', 200, item => {
  // this code will be repeated for all divs.
  item.classList.add('what_ever_you_want')
})
