« Floats were intended to be used to take small pieces of content out of the flow and let the rest of the text wrap around them. They were not intended to be used for the main content of a page, nor were they designed for it. Nevertheless, use of floats for the main content of a page is quite common today ». David Baron, membre du groupe de travail CSS du W3C, Overuse of floats considered harmful.
« An open group can iterate much faster than a closed group. With an open group we can get test implementations, feedback, tests, and discussion straight away, instead of waiting months and then pulling back the curtain and presenting a fait accompli, at which points comments are perceived more as a pain than a help. », Ian Hickson, http://ln.hixie.ch/?start=1181118077&count=1.

plus généralement, « De nombreuses participants à la liste de discussion www-talk, le lieu de rencontre électronique de la première communauté web, étaient d'accord sur le fait que le web tirerait profit des feuilles de styles. Cependant, il y avait un désaccord sur le point de savoir s'il avait besoin d'un nouveau langage de feuille de style ou si l'un des langages déjà existants, créés au départ pour la publication imprimée, suffirait à ses besoins ».

« Au bout du compte, la possibilité d'être lu et écrit par l'humain avait une valeur ajoutée plus élevée que la possibilité de réutiliser des analyseurs syntaxiques existants », Håkon Wium Lie, Cascading Style Sheets, Thesis submitted for the degree of Doctor Philosophiœ, Faculty of Mathematics and Natural Sciences, University of Oslo, Norway, 2005, http://people.opera.com/howcome/2006/phd/#ch-problems.
« CSS2 offers a mechanism for describing and selecting fonts from the web. However, the feature is not much used. Two major reasons for this might be: First, there is no universal font format which all vendors support; and second, font designer want to be compensated for their work and no suitable payment mechanism is available», Håkon Wium Lie, Cascading Style Sheets, Thesis submitted for the degree of Doctor Philosophiœ, Faculty of Mathematics and Natural Sciences, University of Oslo, Norway, 2005, http://people.opera.com/howcome/2006/phd/#ch-problems.

Un grand nombre de propositions de techniques de styles ont été faites durant les premières années du web. Seules les trois principales sont citées dans l'article, mais toutes ont, à un degré variable, influencé le langage CSS. Voir http://www.w3.org/Style/History/.
Prédécesseur d'Amaya, Arena est le premier navigateur développé par le W3C, à l'origine à des fins de tests de HTML 3.0. Håkon Lie collabora à son développement à partir de 1994 et ce navigateur anticipa de nombreux développement ultérieurs de CSS2. Abandonné par le W3C en tant que plate-forme de test en 1996, Arena fut ensuite temporairement maintenu par le Yggdrasil Computing jusqu'en 1998. Voir http://www.w3.org/Arena/.
« Since its inception Netscape had been sceptical towards style sheets, and the company's first implementation turned out to be a half-hearted attempt to stop Microsoft from claiming to be more standards-compliant than themselves. The Netscape implementation supports a broad range of features - for example, floating elements - but the Netscape developers did not have time to fully test all the features which are supposedly supported. The result is that many CSS properties cannot be used in Navigator 4 ». Bert Bos et Håkon Lie, Cascading Style Sheets, http://www.w3.org/Style/LieBos2e/history/.
« You can Just Ship software with bugs in it to put out a new stable release because it's versioned. The next version replaces the old. You can always fix the leftover bugs in the next version. CSS doesn't have versions. Any problems there are in the way CSS2.1 defines things can't be fixed in CSS3 except maybe by adding really confusing sets of switches. CSS3 cannot change anything in CSS2.1, it can only build on top of it., What is the CSS Working Group Doing?, Cascading Style Sheets Working Group Blog », 2 juillet 2007.
« There is no doubt that we will still find (small) bugs in the specification, but given the type of errors we fixed recently, we have reason to believe that the spec is good enough for implementers and users alike. We want people to start implementing and using CSS 2.1 for real (and tell us about any remaining problems, of course) », Bert Bos, éditeur de CSS 2.1, http://www.w3.org/blog/CSS/2007/07/20/cssan2_1_is_a_candidate_recommendation.
« In such cases, a user agent may implement a subset of CSS. Subsets of CSS are limited to combining selected CSS modules, and once a module has been chosen, all of its features must be supported. », Introduction to CSS3, http://www.w3.org/TR/css3-roadmap/#whymods.
« However, pictures were also a threat to the web. Designers started to encode text in images in order to achieve certain fonts or other special effects. In order for HTML to remain a logical markup language (as opposed to a presentational language) a style sheet language was needed. So, the motivation for developing style sheets was twofold: we wanted to give authors the presentational effects they craved, while stopping HTML from sliding down the ladder of abstraction to become a presentational language », Interview with Håkon Wium Lie, 31 mars 2005, http://www.webstandards.org/2005/03/31/interview-with-hkon-wium-lie/.
