HTML - checkbox input
0 points
In this article, we would like to show you checkbox input element in HTML.
Quick solution:
xxxxxxxxxx1
<input type="checkbox" id="field" checked />2
<label for="field">Option 1</label>or:
xxxxxxxxxx1
<label>2
<input type="checkbox" />3
<span>Option 2</span>4
</label>Note:
By wrapping
inputwith thelabelwe don't need to use theidattribute that can be useful when we work with dynamically generated web pages (React, Angular, etc.).
In this section, we create a simple checkbox by setting input type attribute to checkbox. We also use checked attribute to mark the Red as a default answer.
Note:
The key is that the
labelelements describinginputelements are bound to the inputs using theid-forrelation.
Runnable example:
xxxxxxxxxx1

<html>3
<body style="height: 105px">4
<p>Choose your favorite colors:</p>5
<div>6
<input type="checkbox" id="red" checked />7
<label for="red">Red</label>8
</div>9
<div>10
<input type="checkbox" id="green" />11
<label for="green">Green</label>12
</div>13
<div>14
<input type="checkbox" id="blue" />15
<label for="blue">Blue</label>16
</div>17
</body>18
</html>In this section, we present an alternative solution where input elements are wrapped with label. The solution is equal to the first one but we don't need to specify id attributes.
