Good time.
We ordered the development of the site.
The developers made the site, but the validator swears at the code:
https://validator.w3.org/check?uri=http://nasha-sv
... :
there is no attribute "data-stellar-ratio"
there is no attribute "data-wow-delay"
etc.
The developer rightly draws attention to the fact that these errors are caused by the use of scripts used for animation.
Questions:
1) Is it worth leaving invalid code for the sake of a beautiful animation?
2) How important is code validity for SEO?
3) Is there a way to make invalid scripts valid but work?
4) Is there an option to find valid ways to make the same functionality?

First, the developer needs to look at the root. Why does the site have an obsolete Doctype, namely XHTML 1.0 Strict ? Now HTML 5 is already widely used. Validator errors are due to the fact that, according to the Doctype website, tags should not have fictitious data attributes, and animation scripts want to use them for correct work.
Secondly, for modern SEO it has not been proven that the code validity improves the position of the site in search engines, if there is any coefficient of influence, then it is very meager.

Try changing the title first.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="ru" xml:lang="ru">

to a more tolerant

<!DOCTYPE html>
<html lang="ru">

maybe after that life will sparkle with brighter colors.
UPD, but in general, a valid layout is a good tone, for SEO, I didn’t particularly see that it was highly valued, yes, this is some kind of plus for karma, but as before, for SEO and ranking, the main priority is high-quality and necessary content, and how you design it is different the question is, if information is very important for humanity, believe me, no matter what the layout is, you will always have tops)))))

1) If this animation delays customers and makes them interact with the site (due to which the behavioral factor will increase), then you can leave it. If it's just "pretty", then it's better to optimize or remove it altogether.
2) If promoting under Yandex, then it’s better to do everything using BEMU
3) The site is simple, look for errors and fix them.
4) The site is simple, look for errors and correct them.

It's clear that there are no mistakes at all, but they need to be minimized.
And yet, you have an outgoing broken link on your site to eluxer.net/code?sesscheck=1&id=105&subid=51824_6287_
It is desirable to remove it.
Just the same, the absence of alts will hit SEO the most)
