- 隱藏的內容/元素會到達瀏覽器。雖然使用者看不到它。
- CSS 被添加到所有需要的 CSS 元素的頁面中。

Mechanism of Functioning
Multiple CSS Classes: If multiple visibility control classes are added, ALL of them must meet the criterion to keep the element visible. If any one of them hides the element, it will be hidden. For example: visible_to_group_123 visible_to_group_124 will show the element only to those who have access to both groups.
Hidden data/elements reaches the browser. Though user’s do not see it.
CSS is added to the page for all CSS elements that needs to be hidden based on above rules.
After page is loaded. These elements are removed from page using jQuery (if available), so it won’t be available even on Inspect.
Elements rendered after the page load are hidden but not removed from DOM/page.

Depending on the interest in this feature, we will decide on adding a shortcode and/or a Gutenberg Block to achieve this feature.
