Need help with a page

If you take a look around line 2157 in your css file you’ll see this –

input, 
select, 
textarea {
    background-color: #FFFFFF;
    border: 1px solid #DDDDDD;
    padding: 0.3125rem 0.625rem;
    width: 100%;
}

The width is what is causing that issue. You could either remove that, or individually create a separate class for that particular image so it shows up the size you want……whichever way would be easier for you.
