Popup Maker Glossary of Terms

This is a list of terms with their definitions in alphabetical order. We use these terms throughout the Popup Maker Admin area and our documentation.

! (Not) Operator #

Related Articles
The Not or exclamation point ( ! ) operator checks for the opposite of a targeting condition.

Clicking the exclamation point icon turns the Not operator on and off.

  • A gray icon means the operator is off and the condition acts normally. Off is the default
  • A red icon appears when the operator is on. That means the opposite of the condition takes effect.


  •  All Posts: The popup can display on all posts.
  •  Blog Index: The popup can not display on the blog index page.

A #

Admin / WP Admin / WordPress Admin #

Related Articles
The administration or management area for a WordPress website. This is usually the first page you see when you log into a WordPress site with an Administrator role.

The official WordPress docs call the admin area the Administration Screen. Another popular name you'll see is the admin dashboard.

Once you're logged in with the Administrator role, you'll see the Popup Maker Admin menu.

We use Admin and WP Admin interchangeably in our documentation.

Advanced Targeting Conditions #

Definition Related Articles
Advanced Targeting Conditions are a set of extra popup targeting conditions that come with the premium Advanced Targeting Conditions extension.

These advanced conditions are  non-content based, unlike the standard conditions that come free with Popup Maker. Meaning that they target popups using things like logged-in status, referrer information, or browser and device information. You can use advanced targeting interchangeably with the standard targeting conditions. Access to these conditions requires a premium plugin license active on a site.

Back End #

Definition Related Articles
The part of a website that you can see if you are logged as an administrator. This is the opposite of the front end of your site.

The back end of a site is where you can create posts and pages. It can also mean the webserver admin area where you can do things like make site backups and edit server files.

Conditions #

Definition Related Articles
Conditions are rules you can give a popup on where to display on your site.

See Targeting Conditions for the full details.

Cookies #

Related Articles
Cookies are small files (about 4 KB) that a browser can create on your computer to store information. Cookies help keep track of your website session. 

Popup Maker lets you create cookies to remember when popups get opened. That means you can tell Popup Maker to do things like display a popup only once per visit (session cookie) or month. Popup Maker will check for any relevant cookies before it tries to open a popup.

For example, if you create a popup with a cookie that you set to expire in 30 days, that popup will appear only once in 30 days for each visitor. Let's break that down into 3 common scenarios:

  1. A visitor sees the popup for the first time. The 30-day cookie is set.
  2. If the same person (with the same browser) visits again within 30 days, they won't see that same popup again. The 30-day cookie is still active.
  3. If they visit 30 days after, they can see that popup once again. The original 30-day cookie expires. A new 30-day cookie is set.
Note: If you want a popup always to display, make sure you don't create a cookie for that popup ;-)

CSS (Cascading Style Sheets) #

Definition Related Articles
CSS is what gives style such as color, font, background, animation, and text size to a web page. For example, you can define the color, font, and size of the text on your web page using CSS.

CSS is also smart enough to know the size of the display that you're viewing a web page on. That means you can use CSS to render a mobile-friendly page on smaller devices and a full-size page for wide desktop displays.

Under the covers, CSS is a language that has a syntax for selecting HTML elements and applying style rules to them. Here's an example.

p {
color: red;

The "p" is the CSS selector for the rule. Its job is to find all the "p" elements in a web page. 

The "color: red;" is the rule to apply. Its job is to make the text color red for whatever the CSS selector finds.

So all together, this CSS is saying to make all text in a paragraph the color red. Here's the result.

Want to try? Play with a live demo by changing the color to blue, green, or yellow.

If you're new to CSS, we encourage you to learn more about it.

See also CSS Selectors.


CSS Selectors #

Definition Related Articles
A CSS selector is the part of a CSS rule that selects or matches an HTML element. Any element that matches the selector will get or inherit the styles defined by the CSS rule.

A CSS selector can be a CSS class name (e.g., popmake-15), an HTML ID attribute (e.g., button-1), or even a link.

Popup Maker supports CSS selectors in the following ways:

  • For specifying an HTML element to launch a popup when that element is clicked.
  • For triggering a popup to appear after a specific HTML element is scrolled into view (scroll triggered popups).
  • For displaying popups only if any variation of an HTML element exists on a page (advanced targeting conditions).

Definition Related Articles
The part of a website that anyone on the Internet can see. Think of this as the public-facing side of your website. The front end is the opposite of the back end or admin part of your site.

Hooks #

Definition Related Articles
According to WordPress, "Hooks are a way for one piece of code to interact/modify another piece of code at specific, pre-defined spots."

In plain English, hooks allow you to add custom code to your WordPress site.

Your custom code can change the default actions and filter the default output for:

  • WordPress core
  • Themes
  • Plugins

For example, if you want to add a top notification banner to a Twenty Twenty-One site, you can use the built-in  wp_body_open action hook. Here's what that code would look like.

function custom_content_after_body_open_tag() { ?>
   <div class="top-banner">This is my cool Top Banner!</div>
<?php }
add_action('wp_body_open', 'custom_content_after_body_open_tag');

And, here's the result.

Incognito Mode #

Definition Related Articles
In the Google Chrome browser, opening a browser window in Incognito mode means:

1. You start with a fresh browser session (i.e., no history, no cache, and no cookies).

2. When you close an Incognito window, Chrome does not save your Incognito session's history, cache, and cookies.

3. Chrome saves only bookmarks and file downloads while in Incognito mode.

Going incognito is great for troubleshooting website problems. That's why we always suggest you test your site using an Incognito browser window.

Targeting #

Definition Related Articles
Targeting is a feature that lets you tell where (and even when) to display popups. You create targeting conditions that give rules or instructions for displaying popups.

Targeting is also the tab name under the Popup Settings where you make targeting conditions. Edit your popup, scroll to Popup Settings, and click Targeting to add and manage your targeting conditions.

Targeting Conditions #

Act like filters

Targeting conditions are rules you can create to target where your popup will load and appear (and vice versa). Conditions act like filters for your popups.

For example, you can create a condition for a popup to display only on your homepage or for posts.

No targeting conditions by default

When you create a new popup, it will have * no* targeting conditions by default. 

Having no targeting conditions makes the popup available on all posts and pages. That means new popups get loaded (and can get triggered to display) on every post or page on your site by default. 


We recommend using conditions to limit where a popup loads and appears. Loading your popups only where needed improves your site's efficiency by not loading extra code.

Edit your popup and go to Popup Settings > Targeting to create your targeting conditions today!

Theme Settings Box
