Thanks, dsonesuk - Seems to have sorted that one!

Hi, I am using 'Nu HTML Checker' and it is throwing up the error "Bad value 100% for attribute width on element img: Expected a digit but saw % instead.". Also, the W3 Schools html references says that img width should only be pixels but how can you then scale an image depending on screen size? Using percentages for image width seems to work in Chrome. Have they really not allowed for assigning a percentage to img width??

That is strange Ingolme. If I click on http://www.w3schools.com/howto/howto_js_slideshow.asp and then go down to the first "Try it yourself" (under the "add javascript" and above "Automatic slideshow") then it shows ?s instead of arrows. I now have it working in my program as I have changed the characters as seen in my post above. Thanks for your help on this everyone.

Ok, thanks. Found it here: <a class="prev" onclick="plusSlides(-1)">?</a> <a class="next" onclick="plusSlides(1)">?</a> ....which I changed to: <a class="prev" onclick="plusSlides(-1)">Prev</a> <a class="next" onclick="plusSlides(1)">Next</a> Seems an odd character to put in a demo though. This also works:... <a class="prev" onclick="plusSlides(-1)">❮</a> <a class="next" onclick="plusSlides(1)"❱</a> Max

Thanks for that dsonesuk. Interestingly, if you look at http://www.w3schools.com/howto/howto_js_slideshow.asp you will find that the code doesn't include a reference to the W3 CSS file. However, in Chrome and Oracle I get question marks instead of left/right arrows. The CSS doesn't seem to describe the arrows: /* Next & previous buttons */ .prev, .next { cursor: pointer; position: absolute; top: 50%; width: auto; padding: 16px; margin-top: -22px; color: white; font-weight: bold; font-size: 18px; transition: 0.6s ease; border-radius: 0 3px 3px 0; } If I could get the arrows to work, I feel that it would be a more elegant solution to the question. Thanks again for your comment.

Hello CSS community! I have a general question about slideshows with CSS3 and Javascript. The 'TryItEditor' examples all call http://www.w3schools.com/lib/w3.css which, when you look at it is a huge block of unintelligible (to me anyway) script. e.g.: ---------------------------------------------------------------------------------------------------------------------- "a:active,a:hover{outline-width:0}abbr[title]{border-bottom:none;text-decoration:underline;text-decoration:underline dotted} dfn{font-style:italic}mark{background:#ff0;color:#000} small{font-size:80%}sub,sup{font-size:75%;line-height:0;position:relative;vertical-align:baseline} sub{bottom:-0.25em}sup{top:-0.5em}figure{margin:1em 40px} img{border-style:none}svg:not(:root){overflow:hidden} code,kbd,pre,samp{font-family:monospace,monospace;font-size:1em} hr{box-sizing:content-box;height:0;overflow:visible} button,input,select,textarea{font:inherit;margin:0}optgroup{font-weight:bold} button,input{overflow:visible}button,select{text-transform:none} button,html [type=button],[type=reset],[type=submit]{-webkit-appearance:button} button::-moz-focus-inner, [type=button]::-moz-focus-inner, [type=reset]::-moz-focus-inner, [type=submit]::-moz-focus-inner{border-style:none;padding:0} button:-moz-focusring, [type=button]:-moz-focusring, [type=reset]:-moz-focusring, [type=submit]:-moz-focusring{outline:1px dotted ButtonText} fieldset{border:1px solid #c0c0c0;margin:0 2px;padding:.35em .625em .75em} legend{color:inherit;display:table;max-width:100%;padding:0;white-space:normal}textarea{overflow:auto} [type=checkbox],[type=radio]{padding:0} [type=number]::-webkit-inner-spin-button,[type=number]::-webkit-outer-spin-button{height:auto} [type=search]{-webkit-appearance:textfield;outline-offset:-2px} [type=search]::-webkit-search-cancel-button,[type=search]::-webkit-search-decoration{-webkit-appearance:none} ::-webkit-input-placeholder{color:inherit;opacity:0.54} ::-webkit-file-upload-button{-webkit-appearance:button;font:inherit}" -------------------------------------------------------------------------------------------------------------------------- (this is a small portion). I use html instead of a website editor such as Joomla or Dreamweaver as I am a minimalist and don't like putting huge amounts of code onto the server (giving away my age here). Is there some way that I can produce slideshows myself without recourse to something like this stylesheet. Looking through it, it seems to have catered for every concievable slideshow arrangement that will ever be required. I'd prefer to simplify things if I can. Thanks Max
