Hi Sorry if this is off-topic, but I have been scratching my head for hours and have been frustrated with this error. I am writing this code just for myself. The first stanza in my css code which I moved from HTML to an external css file does not appear to be read at all. This appears to happen whatever the first stanza is, and I have tried moving them around. All other CSS tags are understood, but only if they do not appear in the first stanza. I can give the first two stanzas including the lines above it (all comments). Doesn't look like there is anything wrong here to me, although there is a bit of repetition. Paul ------------------CSS CODE BELOW----------------------------- // Cascading stylesheet for form elements such as buttons // "equal" and "clear" are two class names I gave for form buttons .equal { background-color: #4CAF50; /* Green */ border: 2px solid black; color: white; padding: 4px 7px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; width: 50px; } .equal:hover { background-color: #aefe41; color: black; } .clear { background-color: #FF0000; /* Red */ border: 2px solid black; color: yellow; padding: 4px 7px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; width: 50px; } .clear:hover { background-color: #FFABAB; color: black; }
