Jak přidat vodorovnou čáru do HTML?
Vytvoření vizuálně přitažlivé a dobře strukturované webové stránky často vyžaduje použití vodorovných čar. Tyto řádky mohou pomoci oddělit různé části obsahu a usnadnit uživatelům čtení a pochopení prezentovaných informací. V této příručce prozkoumáme dvě účinné metody přidání vodorovných čar do HTML: pomocí >
vlastnosti značek a CSS.
Různé přístupy k přidání vodorovné čáry v HTML
1. Použití
štítek:
The Horizontální pravidlo t na (
) se používá k vložení vodorovných čar do dokumentu HTML k oddělení částí dokumentu. Je to prázdný nebo nespárovaný tag, což znamená, že není potřeba uzavírací tag.
Příklad: Tento příklad popisuje
tag pro přidání vodorovné čáry.
