how can i get "click" message after hovering over a button through CSS

when I hover on a button, I'm not able to get that message like click or enter or start etc. how can I style my button through css to get that message before actually clicking a button ?

I used things like .button-subscribe:after etc but I am not sure what CSS will actualy work

Solution

You can use a pseudo-element :after as you indicated. Just position it how you want.

.styled {
  border: 0;
  line-height: 2.5;
  padding: 0 20px;
  font-size: 1rem;
  text-align: center;
  color: #fff;
  text-shadow: 1px 1px 1px #000;
  border-radius: 10px;
  background-color: rgba(220, 0, 0, 1);
  box-shadow: inset 2px 2px 3px rgba(255, 255, 255, 0.6), inset -2px -2px 3px rgba(0, 0, 0, 0.6);
  position: relative;
}

.styled:hover {
  background-color: rgba(255, 0, 0, 1);
}

.styled::after {
  content: "Tooltip";
  position: absolute;
  top: 100%;
  left: 50%;
  translate: -50%;
  color: grey;
  border: 1px solid red;
  display: none;
}

.styled:hover::after {
  display: block;
}

<button class="favorite styled" type="button">Add to favorites</button>
