Reduce the width of search result page in Venture theme

[ETTYL]

On my website, the width of the search result page is more than usual. I tried to find the solution but couldn't. Can someone please help me? I am sharing two links- the first is to the search results page and the latter to another page to show how I want the search result page to be.

Search: 14 results found for "bag" – ETTYL (783d52-3.myshopify.com)
Area Rugs – ETTYL (783d52-3.myshopify.com)

You can try this code by following these steps:
Step 1: Go to the online store ->Theme ->Edit Code.
Step 2: Find the theme.liquid file and add the following code above the </head> tag

<style>
@media only screen and (min-width: 750px) {
    .page-width {
        padding: 0 20px !important;
    }
}
</style>

Hopefully it will help you. If yes then Please don't forget hit Like and Mark it as solution!
