Greetings,
Do you have a separate stylesheet for both your HTML pages?
I have worked with different front-end technologies such as jQuery, ReactJs, Angular, Bootstrap, and Tailwind.
Having to work with this diverse range of frameworks and libraries, gave me a keen eye for fixing bugs and resolving problems at an appropriate time.
As a side note, I can keep documentation of your project for future reference, if it suits you, so you can rest assured that you have my future support.
Looking forward to hearing from you,
Best regards.
