In the example below, we are using multiple search textboxes. As you type in the "Search name" textbox, only the name property is searched and matching elements are displayed. Similarly, as you type in the "Search city" textbox, only the city property is searched and the matching elements are displayed. When the "exact match" checkbox is checked, an exact match search is performed.

</html>

Styles.css

 body {
    font-family: Arial;
}
 
table {
    border-collapse: collapse;
}
 
td {
    border: 1px solid black;
    padding: 5px;
}
 
th {
    border: 1px solid black;
    padding: 5px;
    text-align: left;
}

The following example has a single search textbox, and is used to search multiple properties - name and city.
