is it possible to set a Style tag on page of Confluence from page creation API?

[shota.shimizu]

HTML macro is not available in the Confluence Cloud, so some pages cannot be imported as is.

I would like to apply the following Style tags that I was able to display using HTML macros.

<style>
.company-main {
position: relative;
background-color:ffffff;
background-position: 50% 50%;
padding: 40px 20px;
}
.company-main:after {
position: absolute;
z-index: 1;
・・・・

When creating a page via the API like below, I assume it can be created in HTML, butis it possible to set a Style tag?

We would appreciate your confirmation.

Even if you create the page using the API it would not apply the html in cloud so the style tag would not be applied to the confluence cloud page.
