[FYI] Custom Icon inside textbox

[Wikiwi]

To add an icon that represents what you would like your user to put in a specific field, you can do the following:

• Download image files that you would like to use as icons.
• Create a FILE app parameter using the image that you downloaded.
• Add a Header and Footer in your Datapage and disable the HTML editor.
• In your Header, paste the following CSS script:

#InsertRecordFIELDNAME {
    padding-right: 33px;
    background-image: url(PUT_YOUR_APP_PARAMETER_HERE);
    background-position: 97% ;
    background-repeat: no-repeat;
    background-size: 20px;
}

Output: 

Take note that the code above will put the icon on the right side of your text field. If you want it on the left, you can use the below CSS instead:
 

#InsertRecordFIELDNAME {
    padding-left: 33px;
    background-image: url(PUT_YOUR_APP_PARAMETER_HERE);
    background-position: 3% ;
    background-repeat: no-repeat;
    background-size: 20px;
}

Output: 

Replace FIELDNAME with your own field name and do the same thing with the App parameter.

Also, the code above is used in a submission form, if you are using an update form you may need to change #InsertRecord to #EditRecord.
