The CSS code is specific to the theme markup so the CSS code working on one website may not work for others.

You can increase its width on your shared website by adding the below CSS code in the Custom CSS option of Ivory Search plugin settings on the path Ivory Search -> Settings -> Settings

form.is-search-form.is-form-style.is-form-style-3.is-form-id-3851 label {
    width: 90%;
    max-width: 90%;
}

Yes, it is possible using the search form ID passes in the search results page URL.

The search results page is displayed by the search.php file of the theme that you are using on your site so the plugin doesn’t control it but your site theme controls it.

You have to develop custom code in your theme search.php file to achieve this.

If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site or WordPress agency.

You can also consider hiring us to develop it for you using the form https://ivorysearch.com/custom-work/
