jquery set fontsize
In web design, setting the font size of text is a very important factor. In the past, developers would need to manually set the font size of each individual element using CSS. However, with the advent of JQuery, it is now possible to automatically set the font size of all elements programmatically using JQuery. Below we will introduce how to use JQuery to set the font size, and what this feature means for web design.
1. Use JQuery to set the font size
JQuery provides a convenient and quick way to set the font size of all elements containing text. The most commonly used is to use the .css()
method to set the font-size
property. The following is a simple sample code. In this code, we set the font size of all div
elements to 24:
$("div").css("font-size", "24px");
The first parameter in this code is the element that needs to be operated. The selector, the second parameter is the set attribute and value. We can also set multiple properties at the same time via chain syntax:
$("div").css({ "font-size": "24px", "background-color": "red", "color": "white" });
In this example, we set font-size
, background-color
and color
Three attributes. These attributes apply to all div
elements simultaneously.
2. Significance to web design
Font size is a very important element in web design. Using JQuery to set the font size can bring the following benefits:
- Unified style
Using JQuery can uniformly set the font size of all text elements, making the web page look more unified and coordinated. This feature can make web pages look more professional. - Easier to maintain
Using JQuery can easily maintain the style of all text elements. If you need to change the font size, you only need to change one place. - Improve user experience
Different screens and devices have different requirements for display font size. Using JQuery to set font size can make web pages more adaptable to different platforms and devices, and improve user experience.
In short, using JQuery to set the font size can conveniently, quickly and uniformly set the font size of all text elements. This feature can improve the readability and user experience of web pages, and facilitate web page maintenance and updates.
