Bonjour et merci pour tes conseils.
J'ai procédé à l'opération .zip, j'avais déjà vu ce procédé. J'ai le META-INF, mais pas de OEBPS, j'ai un stylesheet.css, à côté du mimetype, qui doit correspondre:

    padding: 0;
    margin: 0
    }
.S-T1 {
    background-color: transparent;
    font-family: "Times New Roman", serif;
    padding: 0;
    margin: 0

    line-height: 1.2;
    padding: 0;
    margin: 0

.S-T3 {
    font-style: italic;
    padding: 0;
    margin: 0
    }
.S-T4 {
    font-style: normal;
    padding: 0;
    margin: 0
    }

page_styles.css me semble décevant :

@page {
    margin-bottom: 5pt;
    margin-top: 5pt
    }
