Proč se moje tlačítko překrývání mé navigační lišty při rolování?

Question 1

Tohle je můj první čas vytvoření webové stránky pro školní projekt, takže mějte se můj chaotický kód. Můj problém je, že když jsem se posunout s mým navigační panel, který se lepí na horní a prochází přes můj Naučit Více tlačítko, tlačítko překrývá nad navigační lišty. Ví někdo jak to opravit?

Question 2

Tady to máš, z-index, je opravdu dobrý. Když máte z-indexje to v podstatě to, co chcete v přední části. Tak tady jsem dal z-index v .container třídy, a můžete vidět, že navigační lišty je vždy vpředu.

.container
{
    position: sticky;
    top: 0;
    position: -webkit-sticky;

Question 3

Aby se ujistěte se, že navigační panel je nad jakýkoli jiný prvek na stránce by se měl pohybovat z-index hodnoty, které máte na nav volič programů na .container třídy.

Dva css prvky se pak stávají:

.container
{
    position: sticky;
    top: 0;
    position: -webkit-sticky;
    background: #FACABC;
    z-index: 9999;
}
    
nav
{
    
}

Vezměte prosím na vědomí, že i když to nemá žádný dopad na aktuální téma, já bych důrazně doporučujeme, aby restrukturalizovat HTML kódu. Platný HTML dokument má následující horní struktura:

<!DOCTYPE html>
<html>
    <head>
        <title>HighItsKy</title>
        <link href="highitsky.css" rel="stylesheet">
        <!-- other links and meta-information -->
    </head>
    <body>
        <!-- all visible elements from the document: div, p, span ... -->
    </body>
</html>

Jakékoliv jiné prvky, které byste chtěli přidat třeba jít v <head>...</head> oddíl (externí skripty a CSS, meta informace), nebo <body>...</body> sekci (viditelné prvky).

Tady to máš, z-index, je opravdu dobrý. Když máte z-indexje to v podstatě to, co chcete v přední části. Tak tady jsem dal z-index v .container třídy, a můžete vidět, že navigační lišty je vždy vpředu.

.container
{
    position: sticky;
    top: 0;
    position: -webkit-sticky;
    background: #FACABC;
    z-index:1;
}
    
nav
{

    z-index: 9999;
}
/* Nav bar*/
.container nav

Proč se moje tlačítko překrývání mé navigační lišty při rolování?
