Answer

You are actually not syncing the data between components. The main content checked never changes. You have to communicate data between parent and child components or this won’t work. And try using reusable components like instead of creating inputone and inputtwo for same checkbox create a generic checkbox component and pass props to it. It is a good practice and keeps the codebase more manageable in the longer run.

App.vue

<template>
  <div id="app">
    <maincontent :showContent="showContent" />
    <inputcheckbox text="one" v-model="checkedOne" />
    <inputcheckbox text="two" v-model="checkedTwo" />
  </div>
</template>

<script>
import maincontent from "./components/maincontent/maincontent.vue";
import inputcheckbox from "./components/a/inputcheckbox.vue";

export default {
  name: "App",
  components: {
    maincontent,
    inputcheckbox,
  },
  computed: {
    showContent() {
      return !(this.checkedOne || this.checkedTwo);
    },
  },
  data() {
    return {
      checkedOne: false,
      checkedTwo: false,
    };
  },
};
</script>

checkbox component:

<template>
  <div>
    <input
      type="checkbox"
      :checked="value"
      @change="$emit('input', $event.target.checked)"
    />
    {{ text }}
  </div>
</template>

<script>
export default {
  name: "inputcheckbox",
  props: ["value", "text"],
};
</script>

Content:

  <template>
    <div class="container" id="app-container" v-if="showContent">
            <p>Text is visible</p>
    </div>
  </template>

    <script>
       export default {
           name: "maincontent",
           props: ["showContent"]
         }
    </script>
