And styles and scripts is very small (project - multiple banners) and connect them separately makes no sense.
Now I have a JS embeds when the page loads CSS, and itself connects to a separate file, in the end, initially loaded content, and then he throws styles.
You can, of course, initially the parent build to opacity: 0 on page load change to a 1, but I was interested in is the embed code straight into the HTML with webpack.
