Preventing Image Dragging in HTML
Dragging images from web pages can be an unintended feature, especially when you have custom image manipulation or interactions in place. This article delves into a solution to disable this drag behavior for images in HTML documents.
Problem:
How can I prevent an image on my web page from being dragged?
Answer:
To prevent image dragging in HTML, you can utilize the following approaches:
- Direct DOM Manipulation:
Using JavaScript, access the specific image element through its ID or class and set its ondragstart event handler to a function that returns false. This effectively cancels the drag action.
document.getElementById('my-image').ondragstart = function() { return false; };
- jQuery:
If you are using the jQuery library, you can take advantage of its event handling capabilities. Bind a dragstart event handler to all image elements on the page, and within the event handler, prevent the default action to disable dragging.
$('img').on('dragstart', function(event) { event.preventDefault(); });
Example:
Consider the following HTML code:
<img src="my-image.jpg" id="my-image">
Using the solution with jQuery, the JavaScript code would be:
$('img').on('dragstart', function(event) { event.preventDefault(); });
This code would effectively disable dragging for all image elements on the page, including the one with the ID "my-image."

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
