Discussion About Active Link Indicator

Before sharing source code, Let’s talk about it. I created two sections one for creating a menu and other section for its page. I gave id on pages and add the id on menu’s action. For example, I put home pages ID is id= "home-id" and put on Home menu < a href="#home-id"> . Now when you click home on the menu section then its automatically navigate to the home page.

I used HTML Data attribute, The data-* attributes gives us the ability to embed custom data attributes on all HTML elements (more Info). In the menu section, we store data and give unique data id to every menu using data-tab-*. I created 7 menus I put A to G in data-tab, For example, data-tab-A for the first menu and data-tab-B for the second menu.

Now in the page section, I used data attribute with data-tab-panel value. In this section, I also used A to G alphabets. Then I choose the home menu and page to active by default by putting data-active-tab="A". In the CSS section, I put a line for a separate menu and pages. Between the menu and page section, I put the underline effect to create the highlight.

I put a span with 3px height with a color, It’s width is decided according to the menu’s words length using JavaScript. In the main section, I put overflow-x: scroll; and overflow-y: hidden; values, creating a scroll effect. Also I put .main-options::-webkit-scrollbar { display: none; } to hide scroll bar.

In JavaScript Section, I put all controls of styling. I created variable for each section, Then it’s changed according to the environment. I create a loop to check the width of the menu’s words length and change it dynamically. There are many more commands, I can’t explain it in writing, After getting the codes you will understand automatically.

Highlight Current Page With HTML CSS JavaScript Source Code

For Creating This Program You Have to Create 3 files. First for HTML, second for CSS, and third for JavaScript. Follow the steps to creating this without any error.

index.html

Create an HTML file named ‘index.html‘ and put these codes given below.

style.css

Now create a CSS file named ‘style.css‘ and put these codes.

/** code by webdevtrick ( https://webdevtrick.com) **/

function.js

The final step, Create a JavaScript file named ‘function.js‘ and put the codes.

}

(function() {

  var resizeTimeout;
  function resizeThrottler() {
    if (!resizeTimeout) {
      resizeTimeout = setTimeout(function() {
        resizeTimeout = null;
        actualResizeHandler();
      }, 66);
    }
  }
  function actualResizeHandler() {
    positionIndicator();
  }
})();

/** code by webdevtrick ( https://webdevtrick.com) **/

Where do you learn all this?
You don’t seem too old to be highly experienced.
Its too complicated to understand.

I guess this works but you could also just give a class (eg. “active”) to the menu item you clicked, and remove that class from all siblings. That’s like 4 lines of code with Jquery.

Nice solution.
Just wondering though why it does not work if the line is placed between the .. tags which is the usual standard.

Hello Shaan,

thank you a ton for sharing this! I just began to learn to be a Web-developer one day. Actualy a try to figure out why your code (that i changed only a bit) dont work. It would be awesome if you could give me a hint.
