Why doesn't the site change when the file is changed?

Question

PHP

Launched a local site on Open Server. Everything worked up to a certain point.
And then when changing one of the selectors, nothing happened on the site.
I began to check, deleted everything to hell from the style file, as a result, everything on the site is fine ...
Open Server version - 5.2.2, clean, did not change anything in the configs.
Everything changes in the HTML file, in styles, no...
