voici ma feuille de style :
p { font-family: Georgia, "Times New Roman", Times, serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 20px}
h1 { font-family: Georgia, "Times New Roman", Times, serif; font-size: 18px; font-style: normal; font-weight: bold; font-variant: normal}
h2 { font-family: Georgia, "Times New Roman", Times, serif; font-size: 14px; font-style: normal; font-weight: bold}
.titreedito { font-family: Georgia, "Times New Roman", Times, serif; font-size: 20px; font-style: italic; font-weight: bold; color: #FFFF00; letter-spacing: normal; vertical-align: baseline; text-align: center; clip: rect( )}
.texteedito { font-family: Georgia, "Times New Roman", Times, serif; font-size: 14px; font-weight: bold; line-height: 30px}
.pagination { font-family: Georgia, "Times New Roman", Times, serif; font-size: 12px}
.soustitreedito { font-family: Georgia, "Times New Roman", Times, serif; font-size: 12px ; color: #ffff00; font-weight: normal; text-align: center}
.titreimageedito { font-family: Georgia, "Times New Roman", Times, serif; font-size: 9px; background-position: center}
.remarque { font-family: Georgia, "Times New Roman", Times, serif; font-size: 12px; text-align: right; font-style: italic}
a { color: #0066CC; text-decoration: underline;}
a:hover { color: #0066cc; text-decoration: underline; }
A.liensommaire {color: black; text-decoration: none;}
A.liensommaire:hover {color: black;text-decoration: underline;}
en fait, j'ai défini les balises classiques (h1, h2, etc.) et j'ai crée des classes de styles (.texteedito par exemple) que j'applique quand nécessaire.
