2
我有兩個下拉列表，它們按預期工作（它們顯示懸停時的內容），但是，如果我點擊列表外部（左側）的區域，下拉列表仍會顯示。奇怪的下拉行爲css
我已經嘗試修復CSS，但我一直無法指出問題。
有沒有更好的樣式下拉式的方法，因爲我仍然是CSS的新手。
UPDATE：
測試這在Firefox和我無法重現該問題。我如何確保在所有瀏覽器中始終如一地運行？

您已經測試了自己的例子，對不對？如果我超出清單的範圍，清單就會關閉（應該如此）。所以或者這個例子不會給我們提供你遇到的問題，或者你正在經歷這個問題，這讓我質疑你正在使用的瀏覽器。因爲上面的例子按預期工作。 – junkfoodjunkie
@junkfoodjunkie我剛剛在Firefox中測試，它沒有問題。但CSS不會在Firefox中加載。任何建議與我如何解決這個問題有關？ – Maddy
咦？我正在查看你的代碼 - 它顯示了一個藍色的矩形，每邊都有半個圓圈，當我將它懸停在它上面時，它變成綠色，並且下拉選擇菜單。這看起來是一樣的，並且在Safari，Firefox，Chrome和Opera中也是一樣的。你使用的是什麼瀏覽器？ – junkfoodjunkie
