[jQuery][CSS] Etendre le fond d’un mega menu déroulant sur toute la largeur de la fenêtre du navigateur

02/06/2020 / admin

Souvent, le fond d’un menu déroulant occupe l’espace dans la limite de l’élément .container d’une page.

La classe .nav-open sur l’élément body permet de placer un overflow-x: hidden; qui va venir empêcher l’apparition d’un scroll horizontal dans le fenêtre de votre navigateur lorsque le menu sera ouvert.

    body.nav-open {
        overflow-x: hidden;
    }
    .navigation {
        ul .level0 .submenu__container {
            &:before,
            &:after {
                position: absolute;
                z-index: 0;
                content: "";
                width: 50%;
                height: 100%;
                top: 0;
                background: #fff;
            }
            &:before {
                left: -50%;
            }
            &:after {
                right: -50%;
            }
        }
    }
}

body.nav-open {

overflow-x: hidden;

}

.navigation {

ul .level0 .submenu__container {

&:before,

&:after {

position: absolute;

z-index: 0;

content: "";

width: 50%;

height: 100%;

top: 0;

background: #fff;

}

&:before {

}

&:after {

}

    $(document).on('mouseenter', '.navigation', function() {
        $('body').addClass('nav-open');
    }).on('mouseleave', '.navigation', function() {
        $('body').removeClass('nav-open');

[CSS] Habiller l’élément Select de formulaire – les techniques en CSS pur

20/05/2020 / admin

- pure css, mais pas un vrai select: https://codepen.io/himalayasingh/pen/pxKKgd
- pareil : https://codepen.io/miniven/pen/ZJydge

Solution pour remplacer le chevron par défaut par un picto encodé en base64

Rotate an image online, clockwise or counterclockwise
Convert WebP to Base64 online – Champ « Output Format »: CSS Background Image — background-image:url(). Il peut arriver que les double quotes " (dans url("data:image/webp;base64,...");) posent problème dans certains CMS. Il suffit de les retirer. Ne pas oublier également d’ajouter un caractère ; à la fin de la ligne générée.

Code CSS à mettre en place:

select {
    -moz-appearance: none;
    -webkit-appearance: none;
    appearance: none;
    //border: none;
    line-height: 1.3;
