How to make header ignore custom code block?

Site URL: https://www.everythingbydor.com/mixing-mastering

So i added a pricing table html+css code to a page on my website, and something there is affecting the header menu and folders,

how can i make the whole header ignore the custom code, or exclude it from the custom code that way it wont affect it?

here are a few screenshots on how it currently looks:

and here is how it should look like:

heres a link to the code source (im not a web developer by any means and i barely got this to even work, so.. sorry if its messy and stuff lmao)

You mean Mixing & Mastering item?

Edit this code

* {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  -ms-box-sizing: border-box;
  -o-box-sizing: border-box;
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

to

.container {
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  -ms-box-sizing: border-box;
  -o-box-sizing: border-box;
  box-sizing: border-box;
  margin: 0;
  padding: 0;
}

thanks for the reply!
however when i try this it breaks the design, i think it might overlap with the other .container settings after the * settings?

is it possible to make the custom code to work only on the # Code Block ID?

thanks again for the help, appreciate it!
