    Line left under submit button images

    Asked by interknecht on June 04, 2012 at 09:10 PM

    I just noticed today that when I upload images to be used in place of the standard submit button that a little grey line appears below the image after I enter the URL. Any idea what this is?

    This is because the jpg image you used was like this. Please check the image http://d2xcq4qphg1ge9.cloudfront.net/assets/9324/819715/original_join.jpg

    You can correct it by reseting the button image. Like this:


    Please inform us if the issue persist. Thanks.

    If you would prefer to use the original button showed in your screenshot, injecting the following rule will solve the problem:

    .form-submit-button {
    -moz-box-shadow: none;
    -webkit-box-shadow: none;
    box-shadow: none;
