CSS property values are changed gradually so that you can create animation effects. Only numeric values can create animations (such as "margin:30px"). String values cannot create animations (such as "background-color:red").Copy CodeThe code is as follows: $ (' #shang '). Click (function () {$ (' html,body '). Animate ({scrolltop: ' 0px '}, 800);});The above code indicates that the scroll bar jumps to 0, and the page movement speed is

Many webpage designs are confused when designing the webpage layout, and the width and size of the webpage are 800*600 and 1024*768, how many pixels should a webpage be designed? The horizontal scroll bar will appear when it is too wide. Next we will explain the standard size of the webpage design. 1. If the webpage width is within 800 for 600*778, the horizontal scroll bar will not appear. The height is de

First, we need to understand a few concepts1, screen size : That is what we usually say, such as a mobile phone several inches screen. For example, 4.7 inches of apples, 5.5 inches of glory 6. This is said to be in inches (1 inches = 2.54 centimeters).Calculation method: Screen size = diagonal first dimension (cm)/2.54 (cm)generally expressed in inches. 1 inch =2.54cm2. Resolution : The number of pixels displayed on the screen, the more pixels in the unit size, the more clearly the image is disp

However, if we create a form with a value of 800,500, the image is distorted. See the preceding figure. Because we use a square cross-section visual image, but when stretched to the screen display, it becomes glviewport (0, 0,800,500); that is, the displ
