Why is the font in the browser different from the font in the psd layout?

Question

css

I used to use external font connection and switched to @font-family due to connection problems.
I also got acquainted with pixelperfect and comparing the layout with the layout, I found that the fonts are terribly different, although the font is the same 100%
What to do in such a situation? because because of them you can't call my layout pixelperfect

Answer 1

The browser and Photoshop have different font rendering engines, that's all. That is why the results are different.
