Hello everyone.
Maybe One of the important things for the website making some text hidden, it can be the zip password or the secret code or anything in your mind. Okay, but how you can do this? Well, I will give a variant for it. You need only use CSS and Html to install it for your wish and use.
I also put images like how it looks.
  

<div class="well"> <!-- use here your own class panel code -->
<form id="joke-form">
    <label>
        For zip password you should answer the question<Br>
        <span class="scrambled">Create a word from notubt</span>
        <br>
        <input type="text" id = "userinput" placeholder=" type with small " size="10">
    </label>
    <button type="submit">Check</button>
</form>
  <div id="result"></div>

<script>
    $('#joke-form').on('submit', function(event) {
event.preventDefault();
var words = $('#joke-form #userinput').val(); 
console.log(words);
  if (words === "button") {
    $('#result').text("👏 Password is: Arsj22 ");
}
else {
    $('#result').text("Not Right answer.😒 Think more Better");
}
});
</script>
</div>

So As you review up there is the question asking. and The answer is button . the main thing is if you know about CSS and HTML you can edit these codes and use on your own. If you can contact msgs then can add the secret code and change this codebase as your password to secret work as well.
I hope it will be good for your usage. if you have any questions please comment here
