Changer la hauteur du formulaire. Il y a trop d'espace vide autour du formulaire.

J'ai vérifié si je pouvais modifier l'i frame une fois le formulaire intégré dans mon site, mais je ne vois pas de chiffre à côté de la hauteur.  Je voudrais insérer seulement des étoiles de notation, mais elles prennent trop de place et tout se décale.

It looks like the form is incorrectly calculating its own height at 931 pixels of height, rather than 461 pixels. I can see that this is your embed code on the website:

<iframe id="JotFormIFrame" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="//form.jotformeu.com/form/52713890083356" frameborder="0" style="width:100%; height:931px; border:none;" scrolling="no" name="JotFormIFrame"></iframe> <script type="text/javascript">
//<![CDATA[
window.handleIFrameMessage = function(e) {var args = e.data.split(":");var iframe = document.getElementById("JotFormIFrame");if (!iframe)return;switch (args[0]) {case "scrollIntoView":iframe.scrollIntoView();break;case "setHeight":iframe.style.height = args[1] + "px";break;case "collapseErrorPage":if (iframe.clientHeight > window.innerHeight) {iframe.style.height = window.innerHeight + "px";}break;case "reloadPage":window.location.reload();break;}};if (window.addEventListener) {window.addEventListener("message", handleIFrameMessage, false);} else if (window.attachEvent) {window.attachEvent("onmessage", handleIFrameMessage);}if(window.location.href && window.location.href.indexOf("?") > -1) {var ifr = document.getElementById("JotFormIFrame");var get = window.location.href.substr(window.location.href.indexOf("?") + 1);if(ifr && get.length > 0) {var src = ifr.src;src = src.indexOf("?") > -1 ? src + "&" + get : src  + "?" + get;ifr.src = src;}}
//]]>
</script>

As the very first step, please only change the 931px into 461px for height, and see if your form now has the normal height.

In case that the first step alone is not enough, you may also need to remove a part of the script that is under your form. So as a second step, you should replace your embed codes with this one:

<iframe id="JotFormIFrame" onDISABLEDload="window.parent.scrollTo(0,0)" allowtransparency="true" src="//form.jotformeu.com/form/52713890083356" frameborder="0" style="width:100%; height:461px; border:none;" scrolling="no" name="JotFormIFrame"></iframe> <script type="text/javascript">
window.handleIFrameMessage = function(e) {var args = e.data.split(":");var iframe = document.getElementById("JotFormIFrame");if (!iframe)return;switch (args[0]) {case "scrollIntoView":iframe.scrollIntoView();break;case "collapseErrorPage":if (iframe.clientHeight > window.innerHeight) {iframe.style.height = window.innerHeight + "px";}break;case "reloadPage":window.location.reload();break;}};if (window.addEventListener) {window.addEventListener("message", handleIFrameMessage, false);} else if (window.attachEvent) {window.attachEvent("onmessage", handleIFrameMessage);}if(window.location.href && window.location.href.indexOf("?") > -1) {var ifr = document.getElementById("JotFormIFrame");var get = window.location.href.substr(window.location.href.indexOf("?") + 1);if(ifr && get.length > 0) {var src = ifr.src;src = src.indexOf("?") > -1 ? src + "&" + get : src  + "?" + get;ifr.src = src;}}
</script>

Please let us know how it goes.
