Creating buttons that link to different pages

Site URL: https://shuvamkabir.net

I'm trying to add buttons that link to other pages on my website, using jquery and

$('.button').click(function() {
   window.location.href = "https://www.shuvamkabir.net/someotherpage";}) 

However, the links don't appear to work. Clicking does nothing. I'm not sure what I'm doing wrong here. I've included the code for the buttons that I'm using.

<style>
/**/
/*Main Navigation Buttons*/
/**/
.navbuttonsection{
    /*text-align: right;*/
    /*display:none;border-radius:6px;*/
    width:350px;
    /*height:300px;margin:auto;box-sizing:border-box;padding-bottom:35px;*/
    /*z-index: 1;*/
    position: absolute;
    right: 0%;
    /*margin-right: -80px;*/ 
    /*bottom: 25px*/
  }
  .button-nav{
    text-transform:uppercase;
    text-align: right;
    font-size:1.1em;
    letter-spacing:.2em;
    box-sizing:border-box;
    vertical-align:middle;
    width:350px;
    height:50px;
    opacity: 0.5;
    transition: opacity .6s ease-in-out, width .6s ease-in-out, right .6s ease-in-out, left .6s ease-in-out, letter-spacing .6s ease-in-out;   
    border-top-left-radius:10px;
    border-bottom-left-radius:10px;
    border-top-right-radius:10px;
    border-bottom-right-radius:10px;
    background-color: white;
    color: black
  }
  .button-nav:hover{
    opacity: 0.8;
    width:100%;
    left: 10%;
    letter-spacing: .3em;
  }
</style>
