 <p>In dit artikel wordt ingegaan op het gebruik van <a href="/nl/docs/Web/CSS">CSS </a>in <a href="nl/docs/Learn/HTML/Forms/Styling_HTML_forms">HTML</a>-formulieren om moeilijk te stijlen widgetsaan te passen. Zoals in vorig artikel werd aangegeven vormen tekstvelden en knoppen geen enkel probleem in CSS. Hier wordt dieper ingegaan  op de donkere kant van het stijlen van HTML-formulieren.</p>

 <p>Formulieren zijn een van de meest complexe structuren in <a href="/en-US/docs/HTML" title="/en-US/docs/HTML">HTML</a>. Elk basisformulier kan gemaakt worden met elementen en attributen. Door een correcte opbouw wordt een bruikbaar en <a href="/en-US/docs/Web/Accessibility">toegankelijk </a>formulier verkregen.</p>

 <p>De volgende compatibiliteitstabellen trachten een samenvatting te geven van CSS-ondersteuning voor HTML-formulieren. Door de complexiteit van CSS en HTML kunnen deze tabellen niet als volledig beschouwd worden. Zij geven echter een goed inzicht in wat wel en wat niet mogelijk is.</p>

 <p>In dit artikel leert de gebruiker het om <a href="/en-US/docs/HTML" title="/en-US/docs/HTML">HTML</a>-formulieren vorm te geven met gebruik van <a href="/en-US/docs/CSS" title="/en-US/docs/CSS">CSS</a>. Dit is echter niet  zo eenvoudig. Om historische en technische redenen gaan formulierelementen (widgets) en CSS niet zo goed samen. Daarom maaken veel ontwikkelaars hun eigen HTML widgets om de vormgeving van formulieren in eigen hand te houden. Dankzij de moderne browsers hebben webontwikkelaars meer en meer controle over het ontwerp van formulierelementen.</p>
