什么是检查网站宽度最准确的自动方式？

Question

I have a script that analyzes websites. I'm looking to check the width. I understand, not all websites will be able to be checked automatically, but I'm trying to figure out a strategy that will work for most business websites. I'm working in PHP if you are wondering, however an explanation of a strategy might be sufficient without PHP code.

Answer 1

Most websites have dynamic page widths so the width depends on the client's browser/screen width. There is therefore, more often than not, no "set width".
