how to lock content until a specific button is pressed on a css animation using jquery?

so I am creating a game idea for an assignment, and I wanted to lock the 2nd and 3rd main menu buttons until they have completed the game in order, just to force a little extra structure into how people would use the animation/game, we are using css animation, so everything is on a one page html document and one js file.

here is the HTML code:

<!doctype html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Meltdown</title>

        <!-- makes browsers render all elements more consistently. Similar to a CSS reset file -->
        <link rel="stylesheet" href="css/normalize.css">

        <!-- the main style sheet you should edit -->  
        <link rel="stylesheet" href="css/style.css"> 

        <!-- link to PT-Sans font from google fonts --> 
        <link href='http://fonts.googleapis.com/css?family=PT+Sans' rel='stylesheet' type='text/css'>

        <!-- link to local version of jQuery --> 
        <script src="js/jquery-1.11.0.min.js"></script>

        <!-- Link to javascript file  --> 
        <script src="js/script.js"></script>

        <!-- Link to JQuery Library and UI  -->
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>

        <meta name="apple-mobile-web-app-capable" content="yes">

so I wanted <div class="menu2-button button">Multiple choice!</div> to be locked until the person has gone through the work on the <div class="page-study"> and pressed the <div class="p1-button button">Multiple choice!</div>.
then I also wanted the same with <div class="menu3-button button">Fix the circuit!</div> until the button on <div class="page-multiple-choice"> was pressed which is <div class="p2-button button">Fix the circuit</div>.

here are the current functions that are affillated with these elements.

    // --------------------------- Menu Page -------------------------------------

    $('.menu1-button').click(function(){
        transition(".page-study","fade");
    });

    $('.menu2-button').click(function(){
        transition(".page-multiple-choice","fade");
    });

    $('.menu3-button').click(function(){
        transition(".page-circuit","fade");
    });
  

    // --------------------------- Study Page -------------------------------------

    $('.p1-button').click(function(){
        transition(".page-multiple-choice","push-left");
    });

    $('.p2-button').click(function(){
        transition(".page-circuit","push-right");
    });

    $('.p-menu-button').click(function(){
        transition(".page-menu","fade");
    });

any help would be greatly appreciated as this is one of the last major things I need to complete in order to finish it 🙂

I tried adding a class to the button of .disabled, which had onclick=false applied to it, and then a class of .enable which had onclick=true on the buttons, but it ended up blocking me from pressing any of the buttons that were on the screens.
