Hace un tiempo que varios usuarios me han solicitado tanto en los comentarios como en el correo electrónico que publique una entrada sobre como agregar el famoso widget horizontal que muestra las últimas noticias de un blog (este widget se ha vuelto muy popular en muchos sitios web); pues bien hoy veremos como añadir este genial truco a nuestros blogs.
Widget Horizontal de Últimas noticias para Blogger…
Para añadir este truco a tu blog ve a Plantilla, Editar HTML y antes de ]]></b:skin> añade lo siguiente:
/* CSS News Ticker */
.ticker-wrap{display:block;text-align:center;margin:0 20px 20px 20px;padding:2px;background:#fefefe;border:1px solid rgba(0,0,0,0.1);border-left:5px solid #3cc091}
.ticker-wrap>span{display:inline-block;background:#fefefe;padding:0;font:700 13px 'roboto',sans-serif}
.ticker-wrap>span>a{color:#222;text-decoration:none}
#ticker{height:45px;overflow:hidden;background:#fefefe;text-align:left}
#ticker ul{padding:0;margin:0;list-style:none}
#ticker ul li{height:45px;white-space:nowrap}
#ticker ul li img{float:left;width:35px;height:35px;margin:5px 7px 5px 5px}
#ticker ul li h3{margin:0;font:700 16px 'roboto',sans-serif}
#ticker ul li h3 a{color:#333;text-decoration:none;line-height:25px!important}
#ticker ul li .tickermeta{font:400 13px 'roboto',sans-serif;line-height:20px!important;color:#999}
Ahora antes de </body> añade lo siguiente:
<script type='text/javascript'>

</script>
Ahora justo debajo de <body> pega lo siguiente:
<div class='ticker-wrap' data-domain='URL DE TU BLOG'>
<div id='ticker'>
</div>
</div>
Ahora reemplaza lo resaltado en color azul por la URL de tu blog en el siguiente formato: miltrucosblogger.com
Guarda los cambios y disfruta de este genial truco.
