Elemente überlappen sich

kingethelred · 1. Mai 2019

Guten Tag ich hab das Problem, dass ich eine Mysql Tabelle in PHP dynamisch anzeigen lasse und der Footer überlappt den untersten Eintrag, wie kann man dieses Problem beheben?

PHP

<!DOCTYPE html>
<html>
<head>
<title>Titel</title>
<meta charset="utf-8">
<meta name="description" content="">
<meta name="author" content="">
<meta name="keywords" content="">
<link rel="stylesheet" type="text/css" href="style_katalog.css"/>
<link href="http://allfont.de/allfont.css?fonts=grand-hotel" rel="stylesheet" type="text/css" />
<script type="text/javascript">
function titel_radio_button_clicked(){
document.getElementById('titel_radio_button').checked = true;
document.getElementById('autor_radio_button').checked = false;
}
function autor_radio_button_clicked(){
document.getElementById('titel_radio_button').checked = false;
document.getElementById('autor_radio_button').checked = true;
}
</script>
</head>

if ($textbox_result!="") {

$db_erg = mysqli_query( $db_link, $sql );
if ( ! $db_erg )

Häufiges Problem, wenn man ein Element fixiert: Gib dem body ein geeignetes margin-bottom.
