] | ASP.NET renders html at client side and css is applied to html. You cannot use HyperLink , Label etc.
```
Label renders to <Span>
Hyperlink to <a>
TextBox to <Input>
```
try
```
a
{
font-family:Times New Roman;
}
input
{
font-family:Tahoma;
}
```
Instead, its better to assign ID's to them and use the ids ... | u can assign class to controls in aspx file as
```
<asp:TextBox ID="txtName" runat="server" CssClass ="txtInput" />
```
and in css file
```
.txtInput
{
font-family:Tahoma;
}

] | You are trying to access the values in an associative array using numeric indexes. Use the column names instead. `mysqli_fetch_assoc()` returns an associative array.
Instead of this,
```
$get_row[1]
```
Try to use this,
```
$get_row['column_name']
```
