Help with responsive menu layout

Hi, I'm an old webdev who is rusty in CSS; I learn about calc() recently and never really learnt display: flex properly.

I made some webs with a responsive menu layout (relevant CSS code posted on bottom). I tried using flex but I still had to do one ugly hack: I have the menu heights for the different resolutions hardcoded and I have to update them manually every time a new chapter is added. It's not a big deal, but I would like to know if there is a proper way to do this.

Some alternatives I've thought about:

The new round(), but it's too new and not supported by most browsers.
JavaScript

... but I feel like there must be a clean CSS-only way to achieve this.

Thanks!

Relevant CSS code (link to full stylesheet in case I missed something).

        ul {
      display: flex;
      flex-direction: column;
      flex-wrap: wrap;
      height: 624px; /* =27x23+3 | 23 = 91/4 */
      margin: 0;
      padding: 16px 16px 4px 16px;
      vertical-align: top;
    }
    @media screen and (max-width: 1000px) {
      ul {
        height: 840px; /* =27x31+3 | 31 = 91/3 */
      }
    }
    @media screen and (max-width: 582px) {
      ul {
        height: 1245px; /* =27x46+3 | 46 = 91/2 */
      }
    }
    @media screen and (max-width: 400px) {
      ul {
        height: auto;
      }
    }
      ul li {
        list-style-type: none;
        margin: 2px 16px 2px 4px;
        font-size: 120%;
      }

      }
        ul li a:first-child {
          width: 106px;
          margin-right: -3px;
        }
        ul li a:hover {
          background-color: #144c48;
          color: #fff;
          border: solid 1px #fff;
        }
