使用 Bootstrap 時遇到問題

[英]Having trouble with Bootstrap

 原文  2019-04-09 14:41:20  4   4    javascript/ html/ css/ bootstrap-4/ s7-1200

問題描述

我最近開始使用 bootstrap 來制作一個適用於電腦和手機/平板電腦的網站。 雖然它可以很好地縮放瀏覽器中的所有內容，但當我調整瀏覽器窗口的大小時，一些文字會在我的界面中消失。 我怎樣才能使我的文本不會消失並留在各自的矩形中？

我在西門子 S7-1200 PLC 上運行這個網頁。 我制作了一個 json 文件，它從我在我的網站上代表的 PLC 獲取數據。 然而，當我在手機上嘗試時，一些文本消失了。 下圖表示我的頁面在筆記本電腦上的網絡瀏覽器上的外觀： 在此處輸入圖片說明

當我調整瀏覽器大小時，它看起來如下所示： 在此處輸入圖片說明

請注意我添加的箭頭，箭頭指向“Mixer 1”文本旁邊的“1”。 對不起，我的英語不是我的母語。

4 個解決方案

解決方案1
 1 已采納  2019-04-09 14:56:29

您的<DIV>文本被包裹在它下面的框中，為.col {}和.col-pixel-width-100 {}下的 DIV 添加white-space: nowrap到您的 CSS

.col {
    height: 100px;
    font-size: 25;
    font-weight: bold;
    text-align: center;
    vertical-align: middle;
    line-height: 98px;
    border: 1px solid black;
    background-color:lightgray;
    white-space: nowrap;
}

.col-pixel-width-100 { 
    font-size: 40;
    font-weight: bold;
    text-align: center;
    vertical-align: middle;
    line-height: 100px;
    flex: 0 0 15%; 
    background-color:grey;
    white-space: nowrap;
}

解決方案2

您也可以嘗試添加“text-nowrap”類。 這是一個 bootsrtap 類，基本上與 Bob Dole 上面建議的相同

解決方案3

您可以簡單地為所有必需的列提供一個新類。 在這里，我為您編輯了代碼

.header {
  background-image: url('../img/test.png');
  background-size: cover;
  background-position: center;
  position: relative;
}

.overlay {

  min-height: 100%;
  min-width: 100%;

.customTable {
    padding-top: 8%;
    padding-left: 2%;
    width: 98%;
}

.col {
    height: 100px;
    font-size: 25;
    font-weight: bold;
    text-align: center;
    vertical-align: middle;
    line-height: 98px;
    border: 1px solid black;
    background-color:lightgray;

.col-pixel-width-100 {

    font-weight: bold;
    text-align: center;
    vertical-align: middle;
    line-height: 100px;

.newclass {
  min-width: 300px;
}

#Auto {
    width: 180px;
    height: 100%;
}
#Handmatig {
    width: 180px;
    height: 100%;
}

PS我添加了一個名為“newclass”的新類並提供了一個最小寬度....請根據需要更改最小寬度

我認為您的問題在於使用 line-height 作為垂直對齊，因為當文本換行時，它會用 98px 的 line-height 換行。

我會先移除它並用填充等重新對齊它。
