How to store individual CSS styling in a database?

Thank you for helping people and contributing to the open source.

I have a Vue.js to-do app. Data is stored in firebase via vue-fire and firestore. I have a function which checks the todo item done by clicking it. But this styling disappears whenever the page is refreshed.

How can I make "line-through" style(or any other) get stored in the data so that even when refreshed it stays there?

   <template>
      <div class="pt-3">
        <div v-show="showText == true" class="text">
          <h2>Get started by adding a new todo.</h2>
          <p>Click on the item to check it done.</p>
          <p class="warnings">This is a prototype app. Please do not input any sensitive information!</p>
        </div>
        <v-row class="addtodo d-flex justify-center">
          <v-col cols="8">
            <v-text-field
              class="addtext"
              label="New Todo"
              outlined
              v-model="newItem"
              @keyup.enter="addItem"
            ></v-text-field>
          </v-col>
          <v-col cols="1">
            <v-btn class="btn" large color="primary" :disabled="newItem == ''" @click="addItem">Add</v-btn>
          </v-col>
        </v-row>
        <transition-group class="d-flex flex-column justify-center align-center" name="fade">
          <v-card
            class="d-flex justify-center align-center ma-2 text-left"
            width="400"
            v-for="(ToDo, index) in ToDos"
            :key="ToDo.id"
        @click="checked = !checked"
          >
            <v-row class="d-flex justify-space-around">
              <v-col cols="8">
                <v-list-item-title     
            :class="{ done: checked }" class="headline mb-1">{{ index + 1}} - {{ ToDo.name }}</v-list-item-title>
              </v-col>
              <v-col class="tools text-right">
                <v-btn class="dicon" icon color="secondary" @click="editToDo(ToDo.id)">
                  <v-icon>mdi-pencil</v-icon>
                </v-btn>
                <v-btn class="dicon" icon color="red" @click="deleteToDo(ToDo.id)">
                  <v-icon>mdi-delete</v-icon>

          if (this.newItem) {
            await db.collection("ToDos").add({ name: this.newItem });
            this.newItem = "";
          }
          this.deleteText();

I don't see any update method that would enable you update records you have in your database - here's some snippet you can use to apply:

First, bind proper click event (instead existing @click="checked = !checked" one):

@click="updateTodo(ToDo)"

And then in your methods:

updateToDo(ToDo) {
  db.collection("ToDos").doc(ToDo.id).patch({ checked: !ToDo.checked })  // <-- not sure if you have .patch method available here to update only 1 property, but I hope you can figure out how to handle that :)
}

EDIT (probable answer for 1st comment below):

Not sure how your binding with DB works, but I assume that it might work like that:

updateToDo(ToDo) {
  ToDo.checked = !ToDo.checked;
  db.collection("ToDos").doc(ToDo.id).patch({ checked: ToDo.checked });
}
