LocalHost Wordpress sites not loading css after Apache Setup Mac

阅读更多关于 LocalHost Wordpress sites not loading css after Apache Setup Mac

问题 After Upgrading to High Sierra my localhost no longer worked. I followed a number of tutorials and finally got it to work but now my Wordpress sites load but do not load the CSS and Javascript files. When I check inspector it shows that it can not load the files because the directory is wrong. The address bar says localhost/Site-Name but the files are trying to be loaded from localhost/~paul/Site-Name so I must have messed up the configuration somehow.. Hopefully somebody can help. Thanks 回答1

问题 I have a block of code for a navbar on a local only site without a web server that I want to have on many pages. I would have like to have a separate file that has the HTML for the navbar that all the pages reference. That way whenever an update to the navbar needs to be made, it only has to be done once. I'm using this Bootstrap template: https://bootstrapmade.com/demo/Regna/ Years ago, using a different type of navbar system, I was able to achieve this with Javascript. I just referenced the

Chrome browser has different zoom size for “localhost” versus all other web-sites

阅读更多关于 Chrome browser has different zoom size for “localhost” versus all other web-sites

Interestingly, even "file://" responds to the global zoom, but the same set of files acts differently when served as "localhost". I read something about Chrome switching things so what used to be 125% is now called 100%; can
