[EMERGENCY QUESTIONS] what CSS code to hide the User Links ? (Help me)

Dear, Master.
last night I see something forum (forumotions product) and it looks beautiful forum
why look beautiful? because in that forum there is no written form of Index, Portal, Search, and many more.
so Index is represented by a picture house (), the search is represented by a mirror image (), private messages are represented by drawing the Mail (). << yes something like that so essentially in that forum there is no reading, reading is represented by the image.

I guess it seems that using CSS code.

The question:
what CSS code to hide these readings, so that looks just the picture alone. if there is please write here the code

Thanks before
Sorry I'am bad English
