<< Wikipedia:Como formatar texto
Le software usate per Wikipedia, MediaWiki, usa un linguage de etiquettage de typo TeX pro designar formulas mathematic. Le systema genera imagines de formato PNG o etiquettage HTML simplice, dependente super le preferentias del usator e super le complexitate del expression. In le futuro, quando navigatores del web deveni plus intelligente, il essera possibile generar HTML avantiate o mesmo MathML in multe casos.
Le etiquettage de mathematica va inter le etiquettas <math> ... </math>. Le separationes inter le lineas inter iste etiquettas non se monstrara in le resultato final; de facto il es un bon idea render le codice plus legibile per introducer un nove linea p.ex. post cata termino o rango de un matrice.
Non usa iste function como parte de un linea de texto regular, pro evitar que le formulas non se alinea ben e que le typo de litteras sia troppo grande.
Concernente le color de fundo, nota que iste pagina es un pagina special e pro isto ha un fundo jalne. Paginas normal in Wikipedia es blanc, dunque le quadros blanc non essera visibile in uso normal.
