boothstrap from-control input bigger

I’m using boothstrap form-control for my project,
and I want the text area to be bigger for the user to add his text, I don’t want it to be just one line.
Of course I tried to give the input an id and play with his height and width in css.
it doesn’t work. can you please help me?
I need to use an input so putting textare type is not possible as well.
that’s the code from the html:

      />`enter code here`
<div id="formDiv">
  <div class="p-3" id="inputsDiv">
    <div class="input-group mb-3 pt-4" id="inputDiv">
      <span class="input-group-text">Task Info:</span>
      <input
        type="text"
        id="taskInfo"
        class="form-control"
        placeholder="Task Info:"
        aria-label="Task Info:"
        aria-describedby="basic-addon1"
      />
    </div>
    </div>
