HTML

              
                <div class="scroller">
    <p>春は、あけぼの。やうやう白くなりゆく、山ぎは少し明りて、紫だちたる雲の細くたなびきたる。</p>
    <p>夏は、夜。月の頃はさらなり。闇もなほ。螢の多く飛び違ひたる。また、ただ一つ二つなど、ほのかにうち光りて行くもをかし。雨など降るもをかし。</p>
    <p>秋は、夕暮。夕日のさして、山の端(やまのは)いと近うなりたるに、烏(からす)の寝どころへ行くとて、三つ四つ、二つ三つなど、飛び急ぐさへあはれなり。まいて雁(かり)などの列ねたるがいと小さく見ゆるは、いとをかし。日入り果てて、風の音、虫の音など、はたいふべきにあらず。</p>
    <p>冬は、つとめて。雪の降りたるはいふべきにもあらず。霜のいと白きも、またさらでも、いと寒きに、火など急ぎ熾して、炭もて渡るも、いとつきづきし。昼になりて、ぬるくゆるびもていけば、火桶の火も、白き灰がちになりて、わろし。</p>
</div>
