Checkbox should be a more commonly used HTML function, but the checkbox that comes with the browser is often not very good-looking, and the effect is different in different browsers. Below I will share with you the effect of CSS HTML custom checkbox, let’s take a look Bar
Checkbox should be a relatively common HTML function, but the checkbox that comes with the browser is often not very good-looking, and the effects are different in different browsers. Out of the need to beautify and unify visual effects, the customization of checkbox was proposed. Here is a summary of the implementation methods.
Implementation ideas
The main means of pure CSS implementation is to use the simulation function of the label tag. The for attribute of label can be associated with a specific input element. Even if the input itself is not visible to the user, after there is a label corresponding to it, the user can directly replace the native input by interacting with the label label - and this gives us Style simulation leaves room. In short, it is
Hide the native input and leave the style definition process to the label (then why not directly change the style of the checkbox? Because checkbox is the default component of the browser, style changes are not as convenient as label. Many Attributes have no effect on checkboxes, such as background, and label is basically the same as p in style. exists, allowing us to directly use the default checkbox of html, eliminating the trouble of js simulation selection.
demo
Some CSS3 properties in DEMO only have the webkit prefix, so it is recommended to use a webkit-based browser to view this pageHTML code:
<p class="wrap"> <!-- `input`的id必须有,这个是label进行元素匹配所必需的 --> <!-- 可以看到每个input的id和label的“for”属性对应同一字符串 --> <input type="checkbox" id="checkbox01" /> <label for="checkbox01"></label> <input type="checkbox" id="checkbox02" /> <label for="checkbox02"></label> <input type="checkbox" id="checkbox03" /> <label for="checkbox03"></label> <input type="checkbox" id="checkbox04" /> <label for="checkbox04"></label>HTML construction is completed, followed by the corresponding css.
.wrap { width: 500px; background-color: #EEE; border: 2px solid #DEF; } /* 隐藏所有checkbox */ input[type='checkbox'] { display: none; } /* 对label进行模拟.背景图片随便拼凑的,不要吐槽品味*/ /* transition效果是做个背景切换效果,这里单纯演示而已,实际上这个过渡不加更自然*/ label { display: inline-block; width: 60px; height: 60px; position: relative; background: url(//www.chitanda.me/images/blank.png); background-position: 0 0px; -webkit-transition: background 0.5s linear; } /* 利用相邻选择符和checkbox`:checked`的状态伪类来模拟默认选中效果(就是点击后那个勾号的效果) */ /*如果这段代码注释,点击后将没有任何反馈给用户*/ /*因为label本身是没有点击后被选中的状态的,checkbox被隐藏后,这个状态只能手动模拟*/ input[type='checkbox']:checked+label { background-position: 0 -60px; }The effect of the above code is as follows, and it seems to be OK.
I won’t go into details about the specific content of pseudo-elements here (in fact, my knowledge of them is limited to their use. I can’t even understand this, so I won’t mislead others)
/* The effect of pseudo-element is very simple, just define `content`, and the other attributes are the same as ordinary p */
label::after { content: attr(data-name); /*利用attr可以减少css代码量,data-name写在html部分的label属性里*/ display: inline-block; position: relative; width: 120px; height: 60px; left: 100%; vertical-align: middle; margin: 10px; }Of course, since you can use ::after To simulate the text of the label, you can also use ::before to simulate the checkbox style of the label, which will not be analyzed here.
