剛開始使用bootstrap,我遇到了一些問題。我想編輯站點的某些部分的大小,但不能讓他們改變/擔心響應性。例如,在下面的代碼中,我想更改圖標的大小,所以我添加了一個額外的類「大小」,並將寬度設置爲300px,但該更改不是在網站上進行的。我甚至嘗試過使用!重要但沒有成功。另外,我想以同樣的方式改變大臂的高度,但一直不成功。我將如何去改變這些?我是否需要進入引導腳本?另外,當設計一個響應式網站時,我應該使用百分比而不是像素?謝謝你,代碼是在這裏:Bootstrap CSS自定義問題

這是行得通,謝謝!我使用像素來設置.jumbotron的高度,但在調整它的大小時保持不變。如何改變尺寸但保持設計的響應? – natem1270
jumbotron只是文本?我的代碼中沒有看到任何jumbotron css – mlegg
