Many topics include the use of Hebrew words, all of which are shown in transliteration, highlighted and italicized. Move the mouse over such a word to see the definition of the word displayed in a small box. Move the mouse away from the word to see the definition disappear. This will happen for the first occurance of a glossary word on a page, so you don’t see repetition on topic pages.
The first image below shows the phrase b’tzelem Elohim highlighted in green and displayed in italics. In the second image below you can see the small popup displaying the definition when the mouse is placed over the highlighted phrase.
