如何从错误输入向Django输入弹出窗口添加CSS样式

from django import forms

class MyForm(forms.Form):
    name = forms.CharField(max_length=100)
    email = forms.EmailField()
    # 其他字段...

from django.shortcuts import render

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            # 处理表单数据
            # ...
        else:
            # 表单验证失败，将错误信息传递给模板
            return render(request, 'my_template.html', {'form': form})
    else:
        form = MyForm()
    return render(request, 'my_template.html', {'form': form})

<form method="post">
    {% csrf_token %}
    {{ form.name.label_tag }}
    {{ form.name }}
    {% if form.name.errors %}
        <div class="error">{{ form.name.errors }}</div>
    {% endif %}
    <br>
    {{ form.email.label_tag }}
    {{ form.email }}
    {% if form.email.errors %}
        <div class="error">{{ form.email.errors }}</div>
    {% endif %}
    <br>
    <!-- 其他字段... -->
    <input type="submit" value="提交">
</form>

.error {
    color: red;
    font-weight: bold;
}
