J'ai créé une mise en page où tout est centré (avec la technique "margin =" 0 auto ".) Je voulais aussi que l'en-tête et le pied de page soient noirs et étendus des deux côtés lorsque le navigateur agrandit les côtés. La seule solution que j'ai trouvée était d'appliquer le style d'arrière-plan à l'en-tête et au pied de page et d'utiliser une classe à l'intérieur (.container) pour centrer le contenu (je pense que Stack Overflow utilise cette technique). avec le pied de page) Il est agréable, mais je voudrais savoir s'il y a une meilleure façon plutôt que d'ajouter divs supplémentairesdilemme de mise en page: en-tête, contenu et pied de page qui étend horizontalement leur couleur d'arrière-plan (mais qui a en même temps un contenu centré)?

You then added a link, which appears below the HTML table. If you want the link inside the HTML table, just cut and paste it inside the table in place of an "ADD TEXT" statement. Any where text,images,or links need to be, there will be a generated "ADD TEXT" statement in the HTML pages.</p>
