How to change the position of an image using HTML and CSS
HTML is a markup language used in web development and can be used to create web pages, including adding elements such as images. In web design, pictures are an important element that can increase the attractiveness and visual effects of a web page.
The process of inserting images into HTML is very simple, just use the HTML element . In most cases, browsers will default to displaying images in the upper left corner. However, in some cases, it is necessary to place the image at a specific location on the web page. This article will introduce how to use HTML and CSS to change the position of images.
Using HTML attributes
First, we can use HTML attributes to modify the position of the image. In the element, there are two attributes that can adjust the position of the image, namely align and border.
align attribute: This attribute specifies how the image is aligned with surrounding text. This attribute has 4 values, namely left, right, center, and justify. If left is set, the image will be aligned to the left; if right is set, the image will be aligned to the right; if center is set, the image will be centered; if justify is set, the image will be aligned along the edge of the page.
The following is an example of using the align attribute to set the image to center alignment:
border attribute: This attribute specifies the border width and border style around the image. If you set border to 0, you can clear the border.
The following is an example of using the border attribute to set an image to have no border:
Using CSS properties
In addition to using HTML properties, you can also use CSS properties to modify the position and size of images. CSS is a language used for stylesheets to specify styles in HTML documents. Therefore, we can use CSS styles to adjust the image.
1. Use the position attribute
You can use the CSS attribute position to control the layout of elements. This attribute has 4 values:
static: By default, the position of the element is determined by the document flow.
relative: The element is positioned relative to its initial position.
absolute: The element is positioned relative to the nearest positioned parent element.
fixed: The element is positioned relative to the browser window.
In order to modify the position of the image, we can set the position attribute of the image to relative or absolute, and use the top, bottom, left and right attributes to control the position of the element.
The following is an example of moving an image 30 pixels to the right:
2. Use the float attribute
Another attribute that can be used is float. This property floats the element to the left or right, allowing other content to the right or left of the element to fill the page layout. In order to modify the position of the image, we can set the float attribute of the image to left or right, and use the margin attribute to control the position of the element.
The following is an example of floating an image to the right and keeping it on the right side of the page:
Summary
HTML and CSS can be used to change the position of images to achieve better visual effects and web page layout. If you want to modify the image position, you can use HTML attributes (such as align and border attributes) or CSS attributes (such as position and float attributes). Through the use of these attributes, the position and size of images can be easily adjusted to make the web design more beautiful and attractive.

React components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
