I want to make it so the text slide in animation doesn't play on the website load and only plays when the button is pressed. also i am unsure why the text moves lower when the button is pressed.

i have tried using java script as one of the other questions suggested which allowed the button to work but then the problem uccured where the text goes a bit lower whne the button is pressed and im not sure why.

function ani() {
  document.getElementById('textbox-1').className = 'textbox-1';
}
.textbox-1 {
  display: flex;
  justify-content: center;
  align-items: center;
  width: 50%;
  flex-direction: column;
  right: 5%;
  top: 120%;
  position: absolute;
  animation-name: slide-right;
  animation-duration: 2s;
  height: 400px;
  width: 1750px;
  color: #c9cecd;
}

@keyframes slide-right {
  from {
    opacity: 0.1;
    right: 25%;
  }
  to {
    opacity: 1;
    right: 5%;
  }
}
<div class="background">
  <div id="BUTTON">
    <button type="button" onclick="ani()" value="Click"><span></span>Rules</button>
  </div>
  <div class="textbox-1">
    <p id="textbox-1" style="font-family:courier;">

If I understand correctly, you wanted to press the button and have the text fade in while moving to the right. This is not the job of a keyframes animation, but instead a transition between two different states. It is perfectly fine to use javascript to toggle the class moveRight every click, which will change the opacity and move the element. We use the css transition property to set which properties will have a gradual transition. Then when those properties are changed by adding a new class or the document changing, the transition between states will be more gradual.

const rules = document.querySelector(".textbox-1");
function ani() {
  rules.classList.toggle("moveRight");
}
.textbox-1 {
  display: flex;
  justify-content: center;
  align-items: center;
  flex-direction: column;
  opacity: 0;
  transform: translate(-100px, 0);
  transition: opacity 2s, transform 2s;
}

.moveRight {
  transform: unset;
  opacity: 1;
}
<div class="background">
    <div id="BUTTON">
        <button type="button" onclick="ani()" value="Click"><span></span>Rules</button>
    </div>
    <div class="textbox-1">
        <p id="textbox-1" style="font-family:courier;">

However this effect does not require javascript either. Let me give a small demo:

body {
  margin: 0;
}

#rulesCheck {
  display: none;
}

label[for="rulesCheck"] {
  display: block;
  cursor: pointer;
  padding: 1rem;
}

#rulesCheck:checked ~ label[for="rulesCheck"] {
  background: lightblue;
}

#rules {
  opacity: 0;
  transform: translate(-100px, 0);
  transition: opacity 2s, transform 2s;
}

#rulesCheck:checked ~ #rules {
  opacity: 1;
  transform: unset;
}
<input type="checkbox" id="rulesCheck">
<label for="rulesCheck">Rules</label>
<div id="rules">
  Please read the rules!!
</div>
