ELI5: How are spiders able to crate webs from A to B if said points are two trees or poles several metres away from each other?

Saw a line of spider web earlier today stretching across 2 trees that were several metres apart. The web was about 2 metres high off the ground. How exactly did the spider get from point A to B with It's web
?

They let out a web string and let it flow on the wind. The string is sticky, so as soon as it touches the other tree, it attaches there. Afterwards the spider can use that string as a base to create the rest of the web.
