Apply only on certain URLs
The code is applied to the entire website by default. Use this feature to limit the pages on which the code appears. For example, the settings shown in the left screenshot will apply the code to the entire website except for sites with URLs that include the term “category.” You can set additional constraints to match only the pages you desire.
Network wide custom CSS/JS/HTML codes
If the “Apply network wide” option is activated on multisite WordPress installations, any custom CSS/JS/HTML code produced on the main subsite will appear on all other subsites. The Simple Custom CSS and JS Pro plugin must be installed on all subsites where you want the custom code to appear, but the license key does not need to be activated on each subsite for this functionality to function.
Any custom HTML code can be placed in the page’s header, footer, or as a shortcode in a page/post or text widget if given an id. The shortcodes can take variables, so the same shortcode can be shown in several places on your website with minor changes. A shortcode defined in the main subsite with the “Apply network wide” option enabled can be used in any other subsite in a multisite WordPress installation.
Preview the code changes
You can preview the website before saving the code and making the changes live. When you click the Preview Changes button, a new tab will open with a preview page. The created URL in the new tab can be shared with coworkers or clients to get their feedback on the modifications before they go live.
Keep a record of all modifications made to the CSS and JS codes, including the options, date, and user who made the changes. Any two separate revisions can be compared to see what was added, what remained unaltered, and what was removed.
Export and Import CSS and JS codes
These are your codes; use them whatever you see fit. If you wish to reuse the code in another WordPress installation, simply export the code together with all the metadata (excluding the revisions, settings, preview URL, and URL restrictions).
