Cascading Style Sheets (CSS) bieten unendliche Möglichkeiten, das Design einer Website gezielt und individuell zu gestalten. Mit CSS3 sind noch einmal viele Features hinzugekommen, auf die viele Designer schon lange gewartet haben: ob Schattenwürfe, abgerundete Ecken oder die Einbindung von Webfonts – ein genauer Blick auf die neuen Gestaltungsmöglichkeiten lohnt sich. Diese dritte Auflage des CSS Kochbuchs wurde grundlegend überarbeitet, aktualisiert und erweitert. In mehr als 200 Rezepten finden Sie Antworten auf gängige bis vertrackte Problemstellungen, denen Webdesigner immer wieder begegnen. CSS-Grundlagen: Der erste Teil des Buchs beschäftigt sich mit grundlegenden CSS-Techniken. Hier erfahren Sie Wissenswertes über die Auswahl und Gestaltung von Seitenelementen und erhalten Tipps rund um die Typografie fürs Web. Natürlich wird auch der Umgang mit Bildern behandelt. Fortgeschrittenere Techniken: Erfahren Sie, wie Sie Formulare, Tabellen und Listen gestalten und ins Layout Ihrer Seite einbetten. Lernen Sie, wie Sie Links und Navigationen optimal gestalten und Effekte wie Rollover, aufklappbare Menüs oder Tooltips mit CSS erzeugen. Seitenlayout und Design: Mit CSS lassen sich ein-, zwei und mehrspaltige Layouts umsetzen, die Sie wahlweise mit festen oder flexiblen Breiten versehen können. Dank der CSS3-Media Queries können Sie nun auch einfach feststellen, ob mit einem Desktop-Rechner, Smartphone oder Tablet auf Ihre Site zugegriffen wird und deren Ausgabe genau für das entsprechende Gerät optimieren. CSS 2.1 und CSS3: CSS3 ist noch relativ jung und wird nicht von allen Browsern gleich gut unterstützt. Dem trägt das Kochbuch Rechnung, indem CSS3-basierte Lösungen angeboten werden, wenn die Browserunterstützung schon sehr breit ist. Alle anderen Rezepte des Buchs basieren auf CSS 2.1.

Aber wenn der Code nicht sauber ist, kann er ein Entwicklungsunternehmen in die Knie zwingen. Jedes Jahr gehen unzählige Stunden und beträchtliche Ressourcen verloren, weil Code schlecht geschrieben ist. Aber das muss nicht sein. Mit Clean Code präsentiert Ihnen der bekannte Software-Experte Robert C. Martin ein revolutionäres Paradigma, mit dem er Ihnen aufzeigt, wie Sie guten Code schreiben und schlechten Code überarbeiten. Zusammen mit seinen Kollegen von Object Mentor destilliert er die besten Praktiken der agilen Entwicklung von sauberem Code zu einem einzigartigen Buch. So können Sie sich die Erfahrungswerte der Meister der Software-Entwicklung aneignen, die aus Ihnen einen besseren Programmierer machen werden – anhand konkreter Fallstudien, die im Buch detailliert durchgearbeitet werden. Sie werden in diesem Buch sehr viel Code lesen. Und Sie werden aufgefordert, darüber nachzudenken, was an diesem Code richtig und falsch ist. Noch wichtiger: Sie werden herausgefordert, Ihre professionellen Werte und Ihre Einstellung zu Ihrem Beruf zu überprüfen. Clean Code besteht aus drei Teilen:Der erste Teil beschreibt die Prinzipien, Patterns und Techniken, die zum Schreiben von sauberem Code benötigt werden. Der zweite Teil besteht aus mehreren, zunehmend komplexeren Fallstudien. An jeder Fallstudie wird aufgezeigt, wie Code gesäubert wird – wie eine mit Problemen behaftete Code-Basis in eine solide und effiziente Form umgewandelt wird. Der dritte Teil enthält den Ertrag und den Lohn der praktischen Arbeit: ein umfangreiches Kapitel mit Best Practices, Heuristiken und Code Smells, die bei der Erstellung der Fallstudien zusammengetragen wurden. Das Ergebnis ist eine Wissensbasis, die beschreibt, wie wir denken, wenn wir Code schreiben, lesen und säubern. Dieses Buch ist ein Muss für alle Entwickler, Software-Ingenieure, Projektmanager, Team-Leiter oder Systemanalytiker, die daran interessiert sind, besseren Code zu produzieren. Über den Autor: Robert C. »Uncle Bob« Martin entwickelt seit 1970 professionell Software. Seit 1990 arbeitet er international als Software-Berater.
