Disabling Image Dragging on an HTML Page
When incorporating images into web pages, it's often desirable to prevent users from dragging and dropping them. This article delves into a solution that addresses this issue.
To disable the dragging of an image, one can use the ondragstart event. By setting this event to return false for the specified image, dragging is effectively disabled.
document.getElementById('my-image').ondragstart = function() { return false; };
This code assigns the ondragstart event to an HTML element by its ID, in this case my-image. When the user starts dragging the image, the event is triggered, and the return false statement prevents the default drag-and-drop behavior.
For those using jQuery, a slightly different approach can be employed:
$('img').on('dragstart', function(event) { event.preventDefault(); });
This code binds a callback function to the dragstart event for all elements on the page. When an image is dragged, jQuery calls event.preventDefault() to suppress the dragging functionality.

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.
