DAWN THEME: How to format Dropdown box text

Hi

Does anyone know how to format the text of the dropdown box –Select category– so that it appears in the same format as the the remaining fields. Also how can I make the Select Category and Message fields required?

Here is the code I’m currently using:

{{ 'section-contact-form.css' | asset_url | stylesheet_tag }}

{%- style -%}
  .section-{{ section.id }}-padding {
    padding-top: {{ section.settings.padding_top | times: 0.75 | round: 0 }}px;
    padding-bottom: {{ section.settings.padding_bottom | times: 0.75 | round: 0 }}px;
  }

  @media screen and (min-width: 750px) {
    .section-{{ section.id }}-padding {
      padding-top: {{ section.settings.padding_top }}px;
      padding-bottom: {{ section.settings.padding_bottom }}px;
    }
  }
{%- endstyle -%}

<div class="color-{{ section.settings.color_scheme }} gradient">
  <div class="contact page-width page-width--narrow section-{{ section.id }}-padding">
    {%- if section.settings.heading != blank -%}
      <h2 class="title title-wrapper--no-top-margin {{ section.settings.heading_size }}">{{ section.settings.heading | escape }}</h2>
    {%- else -%}
      <h2 class="visually-hidden">{{ 'templates.contact.form.title' | t }}</h2>
    {%- endif -%}
    {%- form 'contact', id: 'ContactForm', class: 'isolate' -%}
      {%- if form.posted_successfully? -%}
        <h2 class="form-status form-status-list form__message" tabindex="-1" autofocus>{% render 'icon-success' %} {{ 'templates.contact.form.post_success' | t }}</h2>
      {%- elsif form.errors -%}
        <div class="form__message">
          <h2 class="form-status caption-large text-body" role="alert" tabindex="-1" autofocus>{% render 'icon-error' %} {{ 'templates.contact.form.error_heading' | t }}</h2>
        </div>
        <ul class="form-status-list caption-large" role="list">
          <li>
            <a href="#ContactForm-email" class="link">
              {{ form.errors.translated_fields['email'] | capitalize }} {{ form.errors.messages['email'] }}
            </a>
          </li>
        </ul>
      {%- endif -%}

Anyone know if this is possible?
