Hashtags or #tags are not frequently used in web development the same way they are on social media sites like Twitter or Instagram. However, there are a few situations in which you can use them in web development:
URL Fragments: You can use hashtags as URL fragments to go to particular webpage locations. The browser will scroll to the HTML element on that page that has a matching id attribute when you append a hashtag and an identifier to a URL (for example,
http://example.com/page#section1) (e.g., div id="section1">.../div>). To create a smooth scrolling navigation, this is frequently used for single-page applications (SPAs).
Example:
Code: Select all
<a href="#section1">Go to Section 1</a>
<div id="section1">
<!-- Content of Section 1 -->
</div>
To make code more readable in JavaScript, hashtags are frequently used to create comments or placeholders. They act as annotations or reminders for developers rather than being executed as code.
Example:
Code: Select all
// #TODO: Implement this functionality
function someFunction() {
// Code here
}
To provide additional information or metadata about an element, hashtags can be used as part of data attributes in HTML elements. For later retrieval or filtering, you can store tags associated with content using data attributes like data-hashtag, for instance.
Example:
Code: Select all
<div class="media-content" data-hashtag="webdevelopment,html,css">
<!-- Content here -->
</div>
In some web applications, developers may decide to employ hashtags for special functions like content categorization or filtering. You could, for instance, put in place a system where readers can add hashtags to articles or posts to make them easier to find later.
Example:
Code: Select all
<article>
<h2>Web Development Trends in 2023</h2>
<p>...</p>
<div class="hashtags">
<span>#webdevelopment</span>
<span>#trends</span>
<span>#2023</span>
</div>
</article>
Hash Tags are more like tagging a particular subject which is targetted or trending to highlight and search it which is directly linked like a category. It is like a menu filter but for contents. If some one writes food in search even that is a tag because it is targetting particular category which is linked to a certain subject. In easy way to understand if you have blogs or articles hashtags can be beneficial to find and filter post depending on the categorical or subjectual #TAG the blog posts were tagged with because then you will get more filtered result. It does not effect seo but it does help user usability and increases usability and makes filtering contents easier for users.
In current social media #tags are used to highlight a particular subject and get filtered results or people who tagged there post with the same to be more relevant and related to the topic that they are searching. So in a way it is a filtering strategy which is being used in mainstream media.
It's crucial to remember that the use of hashtags in web development is not standardized, and their functionality or meaning may change depending on the situation. The provided examples show a few typical uses for hashtags, but their application is flexible and is determined by the demands of your project.
