[動くCSSのためのメモスライドショー](https://lopan.jp/css-animation-
slideshow/)を参考にして、スライドショーを作成しました。  
動くようになったのですが、もう少し手を加えたくて投稿しました。

やりたいこと

・次の画像に遷移するためのボタンを透明化して、画像を両サイドいっぱいにしたい。  
-今はlightSeaGreenが設定されているので、そこを透明にするのはできるのですが、画像が思うように両サイドいっぱいにならないで困ってます。  
・高さをもう少し短くしたい。どの部分を変更すれば高さの調節ができますでしょうか。

よろしくお願いします。

question
html css
CSS スライドショーを完成させたい。
> 今はlightSeaGreenが設定されているので、そこを透明にするのはできるのですが、画像が思うように両サイドいっぱいにならないで困ってます。

imgにpaddingがついてますね。こちらを外せば問題ないかと

slideContents に高さを設定すればよろしいと思います。

CSSの調整についてですが  
CSSを試すにはChromeのF12のElementsタブでStyleなどを利用してCSSを動的にいじるとわかりやすいと思います。直接スタイルを変更したり、paddingをなくしたりといった操作が動的に対応ができます。  
一度お試しを。
