Loading a stylesheet on a specific page [duplicate]

Try using parent and child class to use css on specific page

<div class="top-container"><span class="header-text"> content here</span> </div>

Assign a page level class .top-container{}
And then assign use it as a parent class for styling rest of elements on page

.top-container .header-text{}

You do not need to load a separate stylesheet rather than you can load a part of your css file for that specific page
