我一直在努力调整我的导航栏元素导航栏 图片
问题是：
- 将输入 div 和搜索按钮放在品牌形象旁边的左侧。
- 修改输入 div 的宽度。我试过 col-6 但它没有用
贝娄是代码：

aria-label="Search">

</form>
</li>
<li class="nav-item">
<a class="nav-link px-3" href="#"> <i class="fas fa-ticket-alt"></i> Support <span
class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link px-3" href="#"><i class="fas fa-user-plus"></i> Sign up</a>
</li>
<li class="nav-item">
<a class="nav-link px-3" href="#"><i class="fas fa-sign-in-alt"></i> Log in</a>
</li>
<li class="nav-item">
<a class="nav-link px-3" href="#"><i class="fas fa-search"> </i> Search</a>
</li>
</ul>调整导航栏后，我想将其集成到 Struts 1 项目中。我无法向输入 div 添加占位符值。你有什么主意吗？
