Why doesn't container work?

Question

css

I created a section block, then a container block, but the page width is still stretched to the entire monitor. What could have caused this? In the previous project, container worked and was 1140px, but now its width is 1264px.

Here is a piece of code:

<section class="promo">
        <div class="container">
            <div class="promo__logo">
                <img src="icons/main_logo.png" alt="">
            </div>
        </div>
    </section>

Compare your container styles with mine, if you don't find the error yourself, drop the css styles, or a screenshot of the container in devtools. Or a link to a website.
