Creating Modal using HTML and CSS

when we want to add a modal instead of a global view message, we can add it simply using HTML and CSS.

.modal-container {
    margin: 0 auto;
    padding-top: 5px;
    position: relative;
    
  }

  
  .modal-container .modal-backdrop {
    height: 0;
    width: 0;
    opacity: 0;
    overflow: hidden;
    transition: opacity 0.2s ease-in;
  }
  
  .modal-container #modal-toggle {
    position: absolute;
    left: 0;
    top: 0;
    height: 100%;
    width: 100%;
    margin: 0;
    opacity: 0;
    cursor: pointer;
  }

.modal-container #modal-toggle:checked {
  width: 100vw;
  height: 100vh;
  position: fixed;
  left: 0;
  top: 0;
  z-index: 9;
  opacity: 0;
}

.modal-container #modal-toggle:checked ~ .modal-backdrop {
  background-color: rgba(0, 0, 0, 0.6);
  width: 100vw;
  height: 100vh;
  position: fixed;
  left: 0;
  top: 0;
  
  pointer-events: none;
  opacity: 1;
}

.modal-container #modal-toggle:checked ~ .modal-backdrop .modal-content {
  background-color: #fff;
  max-width: 400px;
  width: 100%;
//   height: 280px;
  padding: 10px 30px;
  position: absolute;
  left: calc(50% - 200px);
  top: 12%;
  border-radius: 4px;

  pointer-events: auto;
  cursor: auto;
  box-shadow: 0 3px 7px rgba(0, 0, 0, 0.6);
}
@media (max-width: 400px) {

.modal-container #modal-toggle:checked ~ .modal-backdrop .modal-content { left: 0; }
}

.modal-container #modal-toggle:checked ~ .modal-backdrop .modal-content .modal-close {
  color: #666;
  position: absolute;
  right: 2px;
  top: 0;
  padding-top: 7px;
  background: #fff;
  font-size: 16px;
  width: 25px;
  height: 28px;
  font-weight: bold;
  text-align: center;
  cursor: pointer;
}
