原理是被label標籤包裹的input與該label是綁定的,點擊該label內的元素也觸發check,於是可以將標籤內的input隱藏,換上自訂圖片或者自訂css樣式。
利用after虛擬元素自訂radio
好處就是少寫個標籤清爽些,看起來比較簡潔
<label><input name="year" type="radio"><span>2011</span></label><label><input name="year" type="radio" checked><span>2012</span></label><label><input name="year" type="radio"><span>2013</span></label>
label input[type="radio"] { appearance: none; -webkit-appearance: none; outline: none; margin: 0; } label input[type="radio"]:after { display: block; content: ""; width: 12px; height: 12px; background: #fff; border-radius: 50%; border: 2px solid #bfbfbf; } label input[type="radio"]:checked:after { background: #0593d3; border: 2px solid #fff; }

再試試利用圖片自訂,這次不用after虛擬元素了,多加一個i標籤,對標籤設定背景圖片,check狀態再換一張。
先準備兩張小圖片,當然,實際生產中請合并,不然一堆小圖片塞滿請求,影響體驗。
這是UI同事準備的兩張小圖,不厚道的直接拿來用了..
<label class="custom-checkbox"><input class="check-zhengshe" type="checkbox"><i></i><span>check1</span></label><label class="custom-checkbox"><input class="check-wapian" type="checkbox"><i></i><span>check2</span></label><label class="custom-checkbox"><input class="check-zhengwu" type="checkbox"><i></i><span>check3</span></label>
