Align button to textarea corner-CodePudding

I have a text_area and I want a two of buttons to be below the text_area and aligned with the text area's bottom right corner to be like:

What I have so far is below code:

form with modal

<%= form_for @note, :url => registrant_notes_path(@registrant), remote: true do |f| %>
  <div >
    <%= f.label :body, 'Add note' %>
    <%= f.text_area :body, maxlength: 1000, id: "review_text" %>
    <%= show_errors(@note, :body) %>

    <div >
      <span id="counter" data-maximum-length="1000"><%= 1000 %></span> chars left / 1000 character max
    </div>
    <%= f.hidden_field :administrator_id, value: current_login.id %>
    <%= f.hidden_field :registrant_id, value: @registrant.id %>
  </div>
  <div >
    <button type="button"  data-dismiss="modal">Close</button>
    <%= f.submit "Save", class: "btn btn-primary" %>
  </div>
<% end %>

css

.modal-footer {
    border-top: 0 none;
}

.counter-text {
  border-top: 0 none;
  text-align: right;
}

#review_text {
  min-height: 54px;
  width: 100%;
}

CodePudding user response：

add padding-right:0; to .moadal-footer

 .modal-footer {
 border-top: 0 none;
  padding-right:0;
 }

add modal-footer section after div modal-body
