[SASS][LESS] BEM, Block Element Modifier, astuces et bonnes pratiques

16/06/2022 / admin

Ressources en ligne sur BEM, Block Element Modifier

Une liste de ressources qui m’ont aidé à comprendre la méthodologie BEM:

Example perso avec un store locator

Regarder notamment le principe d’imbrication de plusieurs BLOCKs et la présence de la classe helper .is-store--china (comment elle est utilisée dans le code LESS ensuite).

Code HTML

<div
    id="storeLocator"
    class="store-locator is-store--china">
        <div class="store-locator__map">
            <div id="mapControl" class="map-control">
                <input
                    type="text"
                    id="autocompleteField"
                    class="map-control--autocomplete__field"
                    placeholder="Enter a place">
                <button
                    id="geolocationButton"
                    class="map-control--geolocation__button">
                    <span>Me localiser</span>
                </button>
            </div>
            <div id="map" class="map">
                <?php // MUST remain empty; here comes the map ?>
            </div>
        </div>
        <div class="store-locator__result">
            <div class="result-filter"></div>
            <div class="result-list">
                <p>Result...</p>
            </div>
        </div>
    </div>
</div>

<div

id="storeLocator"

class="store-locator is-store--china">

<input

type="text"

id="autocompleteField"

class="map-control--autocomplete__field"

placeholder="Enter a place">

<button

id="geolocationButton"

class="map-control--geolocation__button">

<span>Me localiser</span>

</button>

</div>

<?php // MUST remain empty; here comes the map ?>

</div>

<p>Result...</p>

</div>

Code CSS (LESS)

Première explication sous forme de code commenté (pour comprendre)

…mais, ATTENTION: ce n’est pas comme ça que vous devez organiser votre code. Voir la section suivante.

.store-locator {} /* store-locator est un nouveau BLOCK */
.store-locator__map {} /* la map est un ELEMENT (une partie) du store locator comme la main est une partie de la personne */

    .map-control {} /* map-control est un nouveau BLOCK, enfant du BLOCK store-locator */
        .map-control--autocomplete {} /* est un MODIFIER (autocomplete est un type/genre) de map-control comme la femme est un type/genre de personne */
            .map-control--autocomplete__field {} /* field est ELEMENT (une partie) de autocomplete */
        .map-control--geolocation {} /* est un MODIFIER (geolocation est un autre type/genre) de map-control */
            .map-control--geolocation__button {} /* button est un ELEMENT (une partie) de geolocation */

    .map {} /* map est un nouveau BLOCK, enfant du BLOCK store-locator */

.store-locator__result {} /* les result sont un ELEMENT (une partie) du store locator comme la main est une partie de la personne */

    .result-filter {} /* result-filter est un nouveau BLOCK, enfant du BLOCK store-locator */

    .result-list {} /* result-list est un nouveau BLOCK, enfant du BLOCK store-locator (c'est une liste de boutiques ou de retailers mais, par principe d'abstraction, on ne le précise pas */

.store-locator {} /* store-locator est un nouveau BLOCK */

.store-locator__map {} /* la map est un ELEMENT (une partie) du store locator comme la main est une partie de la personne */

.map-control {} /* map-control est un nouveau BLOCK, enfant du BLOCK store-locator */

.map-control--autocomplete {} /* est un MODIFIER (autocomplete est un type/genre) de map-control comme la femme est un type/genre de personne */

.map-control--autocomplete__field {} /* field est ELEMENT (une partie) de autocomplete */

.map-control--geolocation {} /* est un MODIFIER (geolocation est un autre type/genre) de map-control */

.map-control--geolocation__button {} /* button est un ELEMENT (une partie) de geolocation */

.map {} /* map est un nouveau BLOCK, enfant du BLOCK store-locator */

.store-locator__result {} /* les result sont un ELEMENT (une partie) du store locator comme la main est une partie de la personne */

.result-filter {} /* result-filter est un nouveau BLOCK, enfant du BLOCK store-locator */

.result-list {} /* result-list est un nouveau BLOCK, enfant du BLOCK store-locator (c'est une liste de boutiques ou de retailers mais, par principe d'abstraction, on ne le précise pas */

Organisation du code LESS en composants/BLOCKs

Valable pour SASS/SCSS également.

L’organisation du code en parties représentant chacune un block/composant permet le respect du principe d’inception: pas plus de 3 niveaux d’imbrication (à l’exception de la déclaration de :pseudo-classes).

.store-locator {
    display: block;

    &__map {
        height: 100%;
    }

    &__result {}
}

.service-center {}

.boutique-selector {}

.map-control {
    max-width: 50%;

    &--autocomplete {

        &__field {}
    }

    &--geolocation {

        &__button {

            &:hover {}
        }
    }
}

.map {
    height: 100%;
}

.store-locator {

display: block;

&__map {

height: 100%;

}

&__result {}

}

.service-center {}

.boutique-selector {}

.map-control {

max-width: 50%;

&--autocomplete {

&__field {}

}

&--geolocation {

&__button {

&:hover {}

}

.map {

height: 100%;

}

Autre exemple, avec du HTML cette fois:

Le h3 class="store__name" s’affichera:

en rouge si la classe store--is-boutique est présente sur l’élément parent
en gris si la classe store--is-retailer est présente sur l’élément parent

Les autres styles appliqués au h3 class="store__name" seront affectés aux deux.

<a class="store store--is-retailer" href="#">
    <h3 class="store__name">Bartorelli 1882 Spa</h3>

1 2	<a class="store store--is-retailer" href="#"> <h3 class="store__name">Bartorelli 1882 Spa</h3>

.store {

    &--is-boutique & {
        &__name {
            color: #c40d2e;
        }
    }

    &--is-retailer & {
        &__name {
            color: #555555;
        }
    }

    &__name {
        font-weight: 700;
        font-size: 16px;
        text-transform: uppercase;
    }

.store {

&--is-boutique & {

&__name {

color: #c40d2e;

}

&--is-retailer & {

&__name {

color: #555555;

}

&__name {

font-weight: 700;

font-size: 16px;

text-transform: uppercase;

}

Exploitation d’une classe helper `.is-store--china`

L’organisation du code en parties représentant chacune un block/composant est reprise. La classe helper s’intercale au besoin.

Pour <div class="store-locator">, toutes les bordures seront pink.

Pour <div class="store-locator is-store--china">, toutes les bordures seront red.

.store-locator {
    border: 12px solid pink;
    &.is-store--china {
        border: 12px solid red;
    }
    &__map {
        border: 12px solid pink;
        .is-store--china & {
            border: 12px solid red;
        }
    }
}

.map-control {
    border: 12px solid pink;
    &--autocomplete {
        &__field {
            border: 6px solid pink !important;
        }
    }
    .is-store--china & {
        border: 12px solid red;
        &--autocomplete {
            &__field {
                border: 6px solid red !important;
            }
        }
    }
}

.store-locator {

border: 12px solid pink;

&.is-store--china {

border: 12px solid red;

}

&__map {

border: 12px solid pink;

.is-store--china & {

border: 12px solid red;

}

.map-control {

border: 12px solid pink;

&--autocomplete {

&__field {

border: 6px solid pink !important;

}

.is-store--china & {

border: 12px solid red;

&--autocomplete {

&__field {

border: 6px solid red !important;

[jQuery][SASS] Masquer les éléments d’une liste au-delà de 10 et les afficher au clic sur un bouton « Voir plus »

10/11/2017 / admin

Source : nkd-show-more-list sur github. A ready-to-skin show more/show less jQuery/SASS component.

Live demo: https://jsfiddle.net/frontenddeveloper/fp7ntoyg/.

Usage

Just initialize the plug-in on an HTML UL/OL element, ID or class (on an UL/OL element), and set a value within the data-visible-amount attribute. Keep HTML and classes structure.

<script type="text/javascript">
  $(function(){
    $('#myList').nkdShowMoreList();
  });
</script>

<div class="nkd-show-more-list no-js">
  <ul id="myList" class="nkd-list nkd-has-hidden-content" data-visible-amount="4">
    <li class="nkd-list-item">item #01</li>
    <li class="nkd-list-item">item #02</li>
    <li class="nkd-list-item">item #03</li>
    <li class="nkd-list-item">item #04</li>
    <li class="nkd-list-item">item #05</li>
    <li class="nkd-list-item">item #06</li>
    <li class="nkd-list-item">item #07</li>
    <li class="nkd-list-item">item #08</li>
    <li class="nkd-list-item">item #09</li>
    <li class="nkd-list-item">item #10</li>    
  </ul>
  <p class="nkd-actions nkd-hidden">
    <a class="nkd-show-more">
      Show more...
    </a>
    <a class="nkd-show-less">
      Show less...
    </a>
  </p>
</div>

$(function(){

$('#myList').nkdShowMoreList();

});

</script>

</ul>

</a>

Show less...

</a>

[SASS][BEM] @at-root et ampersand

09/11/2017 / admin

Ressources en ligne:

Sass Techniques from the Trenches (version PDF), SUIT, BEM CSS conventions and the power of ampersand. There are loads of articles out there about how to do CSS architectural things like BEM, and articles about the features of Sass, but I think this article does the best job I’ve seen yet of linking between the two and showing how the features of Sass help you right good clean CSS code.

[Responsive design][SASS] Un tableau responsive en mode No More Tables (version 2017)

Sources sur github.com – responsive-tables.

Source de départ: No more tables – This technique was developed by Chris Coyier (@chriscoyier) and described in his post Responsive Data Tables at css-tricks.com. While you’re there, you should probably check out the Responsive Tables Roundup post, which showcases all these techniques and more.

[jQuery] Un carousel avec visuel en pleine page avec n’importe quel plug-in

16/08/2017 / admin

Le but de ce billet n’est pas de donner une solution toute faite mais plutôt une méthode pour étendre rapidement et efficacement les fonctionnalités de n’importe que plug-in jQuery de slider.

HTML

On crée un container dans lequel on place une balise <img> aux attributs non renseignés. Cette balise va servir à accueillir l’image « en cours ».

<!-- Full-page carousel -->
<div id="fullPageCarousel" class="full-page-carousel is-image">
    <img src="" alt="" />
</div>

</div>

jQuery avec la méthode Bind et l’événement DOMSubtreeModified

On crée une fonction qui surveille en temps réel quelle image du carousel est affichée (celle qui possède la plupart du temps une classe .current) et on stocke son URL dans une variable. On assigne ensuite le contenu de cette variable à l’attribut src de notre image en haut de page.

On exécute la fonction au chargement de la page, puis à chaque fois que le DOM relatif au carousel évolue (passage d’une slide à l’autre).

/*
 * full page Carousel
 */
// Use 'default' view of slick carousel
function switchImg(){
  var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-current img').attr('src');
  $('#fullPageCarousel img').attr('src', '').attr('src', getActiveImgURL);
}
switchImg();
$('#block-views-home-slider-block').bind('DOMSubtreeModified', switchImg);

* full page Carousel

// Use 'default' view of slick carousel

function switchImg(){

var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-current img').attr('src');

$('#fullPageCarousel img').attr('src', '').attr('src', getActiveImgURL);

}

switchImg();

$('#block-views-home-slider-block').bind('DOMSubtreeModified', switchImg);

Cas du Slick Carousel (Drupal 7)

Utiliser la méthode .bind() sur l’événement DOMSubtreeModified ne fonctionne pas dans le cas où un changement de slide utilise plusieurs événements. (En réalité,
ça fonctionne, mais le console.log() imprime plusieurs fois l’URL récupérée).

    /*
     * full page Carousel
     */
    // Use 'default' view of slick carousel
    function switchImg(slideIndex){
      if($('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' img').length > 0){
        var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' img').first().attr('src');
        $('#fullPageCarousel img').attr('src', '').attr('src', getActiveImgURL);
      }
    }
    switchImg(0);
    jQuery(document).on('beforeChange', '#slick-views-home-slider-1-slider', function (event, slick, currentSlide, nextSlide) {
      switchImg(nextSlide);
    });

* full page Carousel

// Use 'default' view of slick carousel

function switchImg(slideIndex){

if($('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' img').length > 0){

var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' img').first().attr('src');

$('#fullPageCarousel img').attr('src', '').attr('src', getActiveImgURL);

}

switchImg(0);

jQuery(document).on('beforeChange', '#slick-views-home-slider-1-slider', function (event, slick, currentSlide, nextSlide) {

switchImg(nextSlide);

});

SCSS

On masque les images par défaut du carousel. On met en place quelques styles pour afficher les visuels en pleine page et pour les caler en haut de la fenêtre.

//
// full page carousel
#block-views-home-slider-block {
  img {
    display: none;
  }
}
.full-page-carousel {
  &.is-image {
    img {
      position: absolute;
      z-index: -1;
      top: 0;
    }
  }
}

// full page carousel

#block-views-home-slider-block {

img {

display: none;

}

.full-page-carousel {

&.is-image {

img {

position: absolute;

z-index: -1;

top: 0;

}

Une alternative où l’image est placée en background-image de l’élément body

    /*
     * full page Carousel
     */
    // Use 'default' view of slick carousel
    function switchImg(slideIndex){
      if($('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' .views-field-field-image img').length > 0){
        var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' .views-field-field-image img').first().attr('src');
        $('body')
          .attr('style', '')
          .css({
            'background-image': 'url("'+ getActiveImgURL +'")',
            'background-position': 'top center',
            'background-repeat': 'no-repeat'
          });
      }
    }
    switchImg(0);
    jQuery(document).on('beforeChange', '#slick-views-home-slider-1-slider', function (event, slick, currentSlide, nextSlide) {
      switchImg(nextSlide);
    });

* full page Carousel

// Use 'default' view of slick carousel

function switchImg(slideIndex){

if($('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' .views-field-field-image img').length > 0){

var getActiveImgURL = $('#block-views-home-slider-block').find('.slick-slide.slide--' + slideIndex +' .views-field-field-image img').first().attr('src');

$('body')

.attr('style', '')

.css({

'background-image': 'url("'+ getActiveImgURL +'")',

'background-position': 'top center',

'background-repeat': 'no-repeat'

});

}

switchImg(0);

jQuery(document).on('beforeChange', '#slick-views-home-slider-1-slider', function (event, slick, currentSlide, nextSlide) {

switchImg(nextSlide);

});
