所有的CSS手風琴div的默認（無jQuery的）開放

Question

我使用這個：

jsfiddle.net/wromLbq5

，我希望能有擁有多個手風琴節一次打開的能力，並在頁面加載。我的意思是，當一個人打開時，我不希望另一個人關閉。這可能嗎？沒有JavaScript以及。

（忽略所有的子手風琴too-我只需要一層）

我試圖避免任何Java腳本。 這可能嗎？

Answer 1

不，這是不可能的只有CSS，因爲你的例子使用CSS3 :target選擇器。當你點擊另一個項目時，目標會改變。

你不能用css設置狀態，但你可以設置它的樣式。如果你想保持每個部分打開後點擊你將不得不使用JavaScript，但你不需要jQuery

如果你想使用JavaScript，儘可能接近儘可能模仿CSS，同時允許手風琴繼續開放。要關閉手風琴，只需再次點擊標題即可。

var lists = document.querySelectorAll('.accordion > li > a'); // get list title links 
for (var i = 0; i < lists.length; i++) { // for each list title link 
    lists[i].href = "javascript:void()"; // stop the page from jumping 
    lists[i].onclick = function(e) { // when you click the link 
    var items = e.target.parentNode.querySelectorAll('li'); // get all list items that are siblings of the clicked link 
    for (var x = 0; x < items.length; x++) { // for each list item 
     if (items[x].style.height != '33px') { // if its not open 
     items[x].style.height = '33px'; // open it 
     } else { // otherwise 
     items[x].style.height = '0px'; // close it 
     } 
    } 
    }; 
} 

包裝這個腳本中的標籤，然後要麼在身體的底部掉它，或者在document.onload = function() { /* Script Here */ }

（Demo）把它包

注意同時與:target任何風格選擇器將停止生效，如果用戶禁用了javascript，則應該將它們留在CSS中作爲後備。

Answer 2

這個CSS爲示出使用這種風格的全封閉的手風琴：

.accordion li > .sub-menu li { 
     height: 0px; 
    } 

你可以將它設置爲33px顯示所有打開的網頁打開時 - 但是，因爲它是會破壞功能：目標選擇器，然後設置高度，從而使選定部分顯示爲打開。

唯一的解決辦法是進入javascript .....

Answer 3

可以這樣做嗎？ 是

您是否需要更改HTML？ 是

它漂亮嗎？ 否

基本上代替Target保持狀態。使用checkbox替代您的頂級a標籤與label。
