Custom

Custom source allows you to integrate almost any website into Definer.

Think of it as creating your own personalized reference tool that connects Definer to any website you find useful. Whether you need specialized technical dictionaries, niche translation services, or subject-specific references, the Custom source can handle it all.

Usage

Setting up the Custom source is straightforward and only needs to be done once. After configuration, it works just like any built-in Definer source:

1. Configure the source URL (one-time setup)
2. Select or type a word/phrase you want to look up
3. View your custom content directly in Definer's results

Configuration

To set up or modify your Custom source settings, go to:
Options → Sources → Custom → Settings.

URL

Definer displays your chosen website in what's called an iframe (think of it as a "window" to another website). The URL field determines which website Definer will load in its results window.

Simply enter the website address you want to use as your data source and use {{str}} to represent your search term in the URL.

How to find the right URL

1. Visit the website you want to use as a source
2. Search for a word or phrase using the website's own search function
3. Copy the URL from the address bar into the Custom source settings
4. Replace the search term with {{str}} in the URL

The URL field supports the Liquid Template Language for advanced customization, but in most simple cases you'll only need the {{str}} variable.

CSS

CSS, short for Cascading Style Sheets, is what styles webpages. It allows you to customize how your target website appears in Definer's popup. Since you'll be viewing content in a small popup window, CSS helps ensure only the most relevant information is visible.

Why use CSS?

With CSS, you can:

• Make content more compact to fit better in the popup
• Remove cookie modals, navigation menus, and other distracting elements
• Adjust font sizes and colors for improved readability
• Match the website's appearance to Definer's color scheme

NOTE

Style changes only affect how the website appears in Definer's popup, not the actual website.

CSS Newbie?

No problem! The CSS field is completely optional. You have several options:

• Leave it empty to display the website as-is
• Learn basic CSS (it's easier than you might think!)
• Browse existing examples for inspiration
