How to remove the hover event of css ?
The correct way to cancel and bind hover events in jquery
In web design, we often use jquery to respond to mouse hover events, and The mouseover and mouseout events have the same effect, but how do you use on to bind the hover method? How do you use off to unbind the event?
1. How to bind the hover event
Look at the following code first. Suppose we bind a click and hover event to the a tag:
$(document).ready(function(){ $('a').on({ hover: function(e) {
//Hover event handler
alert("hover"); },
click: function(e) { // Click event handler
alert("click"); } });
});When the a tag is clicked, something strange happens. The bound hover event does not respond at all. The bound click event can respond normally.
But if you change the way of writing, for example:
$("a").hover(function(){ alert('mouseover'); }, function(){
alert('mouseout'); })You should use mouseenter and mouseleave events instead, (this is also .hover( ) events used in the function)
So it can be quoted directly like this:
$(document).ready(function(){ $('a').on({ mouseenter: function(e) {
//Hover event handler
alert("mouseover"); }, mouseleave: function(e) {
//Hover event handler
alert("mouseout"); }, click: function(e) {
// Clickevent handler
alert("click"); } });
});Because .hover() is an event defined by jQuery itself, it is to facilitate users to bind and call mouseenter and It is just a mouseleave event. It is not a real event, so of course it cannot be called as an event parameter in .on().
2. How to cancel the hover event
As we all know, you can use The off function is used to cancel bound events, but it can only cancel events bound through bind. The hover event in jquery is quite special. If the event is bound in this way, it cannot be canceled.
$("a").hover(function(){ alert('mouseover'); }, function(){
alert('mouseout'); })The correct way to cancel the bound hover event:
$('a').off('mouseenter').unbind('mouseleave');

Describe different CSS units and when to use them
Jul 27, 2025 am 04:24 AM
In web development, the choice of CSS units depends on design requirements and responsive performance. 1. Pixels (px) are used to fix sizes such as borders and icons, but are not conducive to responsive design; 2. Percentage (%) is adjusted according to the parent container, suitable for streaming layout but attention to context dependence; 3.em is based on the current font size, rem is based on the root element font, suitable for elastic fonts and unified theme control; 4. Viewport units (vw/vh/vmin/vmax) are adjusted according to the screen size, suitable for full-screen elements and dynamic UI; 5. Auto, inherit, initial and other values are used to automatically calculate, inherit or reset styles, which helps to flexibly layout and style management. The rational use of these units can improve page flexibility and responsiveness.

What are user agent stylesheets?
Jul 31, 2025 am 10:35 AM
User agent stylesheets are the default CSS styles that browsers automatically apply to ensure that HTML elements that have not added custom styles are still basic readable. They affect the initial appearance of the page, but there are differences between browsers, which may lead to inconsistent display. Developers often solve this problem by resetting or standardizing styles. Use the Developer Tools' Compute or Style panel to view the default styles. Common coverage operations include clearing inner and outer margins, modifying link underscores, adjusting title sizes and unifying button styles. Understanding user agent styles can help improve cross-browser consistency and enable precise layout control.
