No space between flex items

There is a website

There must be 2 spaces between the names of the characteristics and their values. I give the code

// такой же код, что и код выше - только для черных пунктов меню типа Моноблоки

Despite the code, there are no spaces. And this is despite the fact that there are spaces inside element <div class="text">'...</div> and also despite the fact that there is a flex element of spaces <div class="spaces">' + ' ' + </div>. Here is the code for convenience https://jsfiddle.net/vladdvin/4stpny16/. How do I get whitespace displayed?
