How to add a template?

Question

Twig

There is a file container.twig
with content

<div class="conatiner">
     <div class="content">
        //тут вывести 
     </div>
</div>

I need to call the .container template in another file and display something inside .content

For example, on one page I need to display the container.twig template and include file1.twig and file2.twig in .content and only file3.twig on another page so that ended up looking like this:

<div class="conatiner">
     <div class="content">
          Контент file1.twig

          Контент file2.twig

           Или что угодно
     </div>
</div>
