Where CSS selectors are used in GTM:
Triggers: You can use CSS selectors to create triggers that fire when a user interacts with a specific element, such as clicking a button, submitting a form, or hovering over an image.
Tags: CSS selectors can be used in custom HTML tags to modify or extract information from specific elements on the page.
How to find CSS selectors:
Inspect Element: Right-click on the element you want to target and select “Inspect” (or “Inspect Element”). This will open the browser’s developer tools.
Find the Element: In the developer tools, locate the HTML code for the element you want to target.
Copy the Selector: Right-click on the HTML code and choose “Copy” -> “Copy selector”. This will copy the CSS selector for the element.
Common CSS selectors:
ID Selector: Targets an element with a specific ID attribute (e.g., #myButton).
Class Selector: Targets elements with a specific class attribute (e.g., .myClass).
Element Selector: Targets all elements of a specific type (e.g., button, a, div).
Attribute Selector: Targets elements with a specific attribute or attribute value (e.g., [href*=”example.com”]).
Combinators: Combine multiple selectors to target elements based on their relationship to each other (e.g., div.myClass p targets all paragraph elements within a div with the class “myClass”).
Tips for using CSS selectors in GTM:
Be specific: Use the most specific selector possible to avoid accidentally targeting other elements.
Test thoroughly: Always test your triggers and tags to ensure they are working as expected.
Use a CSS selector tool: There are many online tools available that can help you find and test CSS selectors.
