Filtrar contenido con CSS y jQuery

Deja un comentario / Por /

Si quieres crear un portfolio y poder filtrarlo por categorías, puedes hacerlo solo utilizando CSS y jQuery. Además podrás crear unos efectos animados que le van a encantar a los visitantes de la página web.

En este artículo te propongo dos diferentes para que puedas escoger el que prefieras.

 

MixItUp

Para ello tienes que crear el archivo html, el css y añadir el jQuery mediante el plugin MixItUp.

 

HTML

Tendrá el siguiente código:

<header class="cd-header">
<h1>Content Filter</h1>
</header>

<main class="cd-main-content">

<div class="cd-tab-filter-wrapper">

<div class="cd-tab-filter">

<ul class="cd-filters">

<li class="placeholder">
<a data-type="all" href="#0">All</a> <!-- selected option on mobile -->
</li>

<li class="filter"><a class="selected" href="#0" data-type="all">All</a></li>

<li class="filter" data-filter=".color-1"><a href="#0" data-type="color-1">Color 1</a></li>

<li class="filter" data-filter=".color-2"><a href="#0" data-type="color-2">Color 2</a></li>

</ul> <!-- cd-filters -->

</div> <!-- cd-tab-filter -->

</div> <!-- cd-tab-filter-wrapper -->


<section class="cd-gallery">

<ul>
<li class="mix color-1 check1 radio2 option3"><img src="img/img-1.jpg" alt="Image 1"></li>
<li class="mix color-2 check2 radio2 option2"><img src="img/img-2.jpg" alt="Image 2"></li>
<li><!-- ... --></li>
<li class="gap"></li>
</ul>

<div class="cd-fail-message">No results found</div>

</section> <!-- cd-gallery -->

<div class="cd-filter">

<form>
<div class="cd-filter-block">
<h4>Block title</h4>
<div class="cd-filter-content">
<!-- filter content -->
</div> <!-- cd-filter-content -->
</div> <!-- cd-filter-block -->
</form>

<a href="#0" class="cd-close">Close</a>

</div> <!-- cd-filter -->

<a href="#0" class="cd-filter-trigger">Filters</a>

</main> <!-- cd-main-content -->

 

Es importante que respetes los estilos, si los cambias tenlo en cuenta para cambiarlos también en el archivo css.

 

CSS

En estos estilos podrás ver muchas transiciones y transformaciones que son necesarias para conseguir que filtre correctamente nuestro contenido.

Aquí te dejo el código del css:

.cd-tab-filter-wrapper {

 background-color: #ffffff;
 z-index: 1;

}

.cd-filter {

position: absolute;
top: 0;
left: 0;
width: 280px;
height: 100%;
background: #ffffff;
z-index: 2;
transform: translateX(-100%);
transition: transform 0.3s, box-shadow 0.3s;

} 

.cd-filter-trigger {

position: absolute;
top: 0;
left: 0;
height: 50px;
width: 60px;
z-index: 3;

}

.cd-main-content.is-fixed .cd-tab-filter-wrapper {

position: fixed;
top: 0;
left: 0;
width: 100%;

}

.cd-main-content.is-fixed .cd-filter {

position: fixed;
height: 100vh;
overflow: hidden;

}

.cd-main-content.is-fixed .cd-filter-trigger {

position: fixed;

}

filtrar-contenido-css-jquery

En la página web del autor puedes ver una demo donde se filtran los contenidos por colores. También te puedes descargar todos los archivos (html, css y jQuery) gratis.

 

 

Blueprint: Filterable Product Grid

Es otro plugin para filtrar contenido. Igual que el anterior te lo divido por partes: en html, en css, javascript y el resultado.

El resultado

Después de todo el código viene el resultado final:

Filtrar contenido con CSS y jQuery

Igual que en el ejemplo anterior, en la página web del autor puedes ver una demo, así como también descargar todos los archivos.

 

Y con esto, este artículo se ha acabado. ¿Te animas a poner en práctica alguno de estos plugins?
