                </div>
                <div class="modal-footer">
                    <input type="submit" class="btn btn-primary" value="Salvar">
                </div>
            </div>
        </div>
    </div>

  </form>

As the other tags are classes, I tried to do this in the ccs file.

number one attempt.

.modal-content{
  width: 500px;
}

try number two

.modal-dialog{
  width: 500px;
}

try number three

.modal-header{
  width: 500px;
}

try number four:

.modal-body{
  width: 500px;
}

It was like this, but it did not work.

Does anyone have any suggestions?
