Answer 1

Bootstrap / CSS

Use col-12, btn-block, w-100, form-control or width:100%

         
             class="col-12"
         
    
         
             class="w-100"
         

         
             class="btn-block"
         
         
         
             class="form-control"
         
         
         
             style="width:100%"
