我有一個非常簡單的待辦事項頁面，我可以在其中輸入成員并將其洗掉或將其標記為已完成。成員是 Bootstrap 警報，到目前為止一切順利。
我的問題是，警報/成員太寬，應該在兩到三列中，以便能夠在螢屏上查看更多。
這就是我卡住的地方，因為網格系統不想要它。我不知道我錯過了什么......
有人可以幫助我，如何將成員串列重新排列為兩列或三列？
我嘗試使用帶有team1按鈕的列。

var y =

` $('#text').val() `</div>`;
$('#memberlist').html(y x);
$('#text').val("");
} else alert("Please, enter the name of the member");
});
//Adding members of team1
$('.btn-team1').click(function() {
if ($('#team1').val().length != 0) {
var members = $('#team1').val().split('\n');
for (var i = 0; i < members.length; i ) {
var x = $('#memberlist').html();
var y =
`<div ><div >
<a href="#" data-dismiss="alert" aria-label="close">×</a>
<b>` members[i] `</b></div></div>`;
if (members[i].trim().length > 0) {
$('#memberlist').html(y x);
}
}
}
});
//Adding members of team2
$('.btn-team2').click(function() {

var members = $('#team2').val().split('\n');

澄清HTML：
- 使用 CSS
margin屬性代替<br> - 使用
text-center類而不是center標簽 - 將頁腳放在
<footer>標簽中 HTML 的末尾 - 使用
.container代替.container-fluid和空列 - 使用層次結構
.form-inline > .input-group > .input-group-btn將輸入和按鈕組織為行內表單
- 使用 CSS
CSS：
- 我洗掉了一些 CSS 指令并恢復了 Bootstrap 容器的原始行為。我建議使用 Bootstrap 4 或 5 和 flex-boxes 來實作更靈活的可能性。
- 我為
form-inline塊添加了樣式以改進其在窄螢屏上的布局。
重做JS：
- 將警報 HTML 代碼包裝在單獨的函式中
addMember - 添加另一個功能，用于通過 textarea 的 id 添加團隊
click借助這兩個功能簡化按鈕的代碼- 使用
.toggleClass()而不是.css()在單擊時更改警報外觀 - 用于
.append()在串列末尾添加新警報
- 將警報 HTML 代碼包裝在單獨的函式中
制作列：
- 將警報包裹在列塊中以將多個警報放在一行中。
- 添加兩個類
col-xs-6 col-sm-4以在移動設備上以 2 列和在寬螢屏上以 3 列組織警報。 - 現在 Bootstrap 的可消除警報是不夠的，因為我們也必須洗掉列塊。所以我們可以洗掉
alert-dismissible類和data-dismiss屬性。我也通過 jQuery 添加了替代成員關閉代碼。

無論您的布局可以改進多少，這里的其他答案已經為您做到了。但是，如果您只想將警報分成 3 列而不必更改整個代碼，只需col-sm-4在您分配值的 JS 行中添加類（它將在小螢屏尺寸的視口上生成 3 列）到y。因此，該特定陳述句現在變為：
var y = "<div class='alert alert-success alert-dismissible fade in'><a href='#' class='close' data-dismiss='alert' aria-label='close'>×</a>" $('#text').val() "</div>";
