How to pass a style from one component to another if condition is true in Vue 3

I have two sibling components where one relies on the other for an event to happen. In this case, I want to apply this styling - marginTop = "-20px"; to the div of one component when the length of an input inside another component is more than 0 characters.

Whether it be props, slots, refs or events, I'm still not sure what fits this use case (I'm very new to Vue). I'm also not sure if I can even pass data between these two sibling components directly or if I have to pass from one child to the parent and then to the other child.

What I'm currently attempting to do is to simply grab the element I want to apply the style to (in the vanilla JS way) and have the method invoked when the aforementioned condition becomes true (all in the same component).

// Component trying to style the element
<ais-state-results v-if="input.length > 0">
// Component trying to style the element
mounted() {
      this.positionSecondaryContent();
},
methods: {
  positionSecondaryContent() {
  const secondaryContent = document.querySelector('.secondary-content');
  secondaryContent.style.marginTop = "-20px";
  }
},
// Component that has the element to be styled
<template>
  <div class="secondary-content">
    <TheWordOfTheDay />
    <SuggestTranslationForm />
  </div>
</template>

Aside from not knowing if I really should be communicating with other components, I'm not sure what to write in the ais-state-results component instance above to attach it to my method and then have the method run as soon as the condition is met.

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
