Read

Discuss

The portfolio gallery is useful when your website contains different types of content or so many contents. With the help of a portfolio gallery, you can easily display all the contents on your front page to the user. But if user wants some specific contents then we need to attach filters on the portfolio. In this article, we will add filters using JavaScript. Before proceeding into this article you can see the article ‘how to create a Portfolio Gallery using HTML and CSS?‘.
Creating Structure: In this section, we will create the basic website structure of the portfolio. Here, we will attach the title attribute so the user can know what will be the content type on each grid of the portfolio.

HTML code: In this section, we will design the basic structure of Portfolio Gallery.

Designing Structure: In the previous section, we have created the structure of the basic website and now we are going to use CSS to design the structure of the web-page.

CSS code:

CSS

/* Wildcard styling */
* { 
    box-sizing: border-box; 
} 
  
/* Padding for whole body */
body { 
    padding: 15px; 
} 
  
.container { 
    max-width: 1200px; 
    margin: auto; 
} 
  
/* Styling h2 tag */
h1 { 
    Color: green; 
    word-break: break-all; 
} 
  
/* Anchor tag decoration */
a { 
    text-decoration: none; 
    color: #5673C8; 
} 
  
a:hover { 
    color: lightblue; 
} 
  
.row { 
    margin: 0px -14px; 
    padding: 8px; 
} 
  
.row>.column { 
    padding: 6px; 
} 
  
.column { 
    float: left; 
    width: 25%; 
    display: none; 
} 
  
/* Content decoration */
.content { 
    background-color: white; 
    padding: 10px; 
    border: 1px solid gray; 
} 
  
/* Paragraph decoration */
p { 
    display: -webkit-box; 
    -webkit-box-orient: vertical; 
    -webkit-line-clamp: 4; 
    overflow: hidden; 
} 
  
.row:after { 
    content: ""; 
    display: table; 
    clear: both; 
} 
  
.content { 
    background-color: white; 
    padding: 10px; 
    border: 1px solid gray; 
} 
  
.show { 
    display: block; 
} 
  
/* Style the filter buttons */
.bttn { 
    border: none; 
    padding: 8px 14px; 
    background-color: gray; 
} 
  
.bttn:hover { 
    background-color: #007EE5; 
    opacity: 0.8; 
} 
  
.bttn.active { 
    background-color: #007EE5; 
    color: white; 
} 
  
/* Window size 850 width set */
@media screen and (max-width: 850px) { 
    .column { 
        width: 50%; 
    } 
} 
  
/* Window size 400 width set */
@media screen and (max-width: 400px) { 
    .column { 
        width: 100%; 
    } 
} 

JavaScript code:

javascript

geeksportal("all") 
  
function geeksportal(c) { 
    var x, i; 
  
    x = document.getElementsByClassName("column"); 
  
    if (c == "all") c = ""; 
  
    for (i = 0; i < x.length; i++) { 
        w3RemoveClass(x[i], "show"); 
  
        if (x[i].className.indexOf(c) > -1) 
            w3AddClass(x[i], "show"); 
    } 
} 
  
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]; 
        } 
    } 
} 
  
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("filtering"); 
var btns = btnContainer.getElementsByClassName("bttn"); 
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"; 
    }); 
}
