I have developed a website utilizing Sitecore XP 10.3, and I am currently encountering an issue wherein the Experience Editor's code is interfering with the functionality of my website. Specifically, the header, which is intended to remain fixed at the top of the page, is being obscured by the Experience Editor ribbon. Additionally, I am experiencing similar conflicts with JavaScript functionality.
Furthermore, I have observed that a YouTube video link is automatically playing upon opening or refreshing the website within the Experience Editor.
Would it be advisable to modify the CSS and JavaScript to accommodate the Experience Editor's requirements?
