</div>
Stap 2) CSS toevoegen:
Voorbeeld
* {
box-sizing: border-box;
}
body {
background-color: #f1f1f1;
padding: 20px;
font-family: Arial;
}
/* Center
website */
.main {
max-width: 1000px;
margin: auto;
}
h1 {
font-size: 50px;
word-break: break-all;
}
.row {
margin: 8px -16px;
}
/* Add padding BETWEEN each column (if you
want) */
.row,
.row >
.column {
padding: 8px;
}
/* Create three equal columns that
floats next to each other */
.column {
float: left;
width: 33.33%;
display: none; /* Hide columns by default
*/
}
/* Clear floats after rows */
.row:after {
content: "";
display: table;
clear: both;
}
/* Content */
.content {
background-color: white;
padding: 10px;
}
/*
The "show" class is added to the filtered elements */
.show {
display: block;
}
/* Style the buttons */
.btn {
border: none;
outline: none;
padding: 12px 16px;
background-color:
white;
cursor: pointer;
}
/* Add a grey background color on mouse-over */
.btn:hover
{
background-color: #ddd;
}
/* Add a dark background color to the active button */
.btn.active {
background-color: #666;
color: white;
}
Stap 3) JavaScript toevoegen:
Voorbeeld
filterSelection("all") // Execute the function and show all columns
function filterSelection(c) {
var x, i;
x = document.getElementsByClassName("column");
if (c == "all") c = "";
// Add the "show" class (display:block) to the filtered elements, and remove
the "show" class from the elements that are not selected
for (i = 0; i < x.length; i++) {
w3RemoveClass(x[i],
"show");
if (x[i].className.indexOf(c) > -1)
w3AddClass(x[i], "show");
}
}
// Show filtered
elements
function w3AddClass(element,
name) {
var i, arr1, arr2;
arr1 = element.className.split("
");
arr2 = name.split(" ");
for (i = 0; i < arr2.length;
i++) {
if (arr1.indexOf(arr2[i]) == -1) {
element.className += " " + arr2[i];
}
}
}
// Hide elements that are not selected
function w3RemoveClass(element, name) {
var i, arr1, arr2;
arr1 = element.className.split(" ");
arr2 = name.split(" ");
for (i = 0; i < arr2.length; i++) {
while
(arr1.indexOf(arr2[i]) > -1) {
arr1.splice(arr1.indexOf(arr2[i]), 1);
}
}
element.className = arr1.join(" ");
}
// Add active class
to the current button (highlight it)
var btnContainer =
document.getElementById("myBtnContainer");
var btns =
btnContainer.getElementsByClassName("btn");
for (var i = 0; i < btns.length;
i++) {
btns[i].addEventListener("click", function(){
var current = document.getElementsByClassName("active");
current[0].className = current[0].className.replace(" active", "");
this.className += " active";
});
}
