Use the <video> tag to embed videos directly in the web page without third-party plug-ins; 2. It is recommended to use the <source> element to provide mp4, webm, ogg and other formats to ensure browser compatibility; 3. Add controls, muted, loop, preload, post and other attributes to improve the playback experience; 4. Automatic playback needs to be matched with muted attributes to avoid being blocked by the browser; 5. Borders, rounded corners, shadows and responsive dimensions can be set through CSS to optimize the video style; 6. Provide fallback text in the tag to prompt browsers that do not support video. Use these methods correctly to achieve native, compatible and beautiful web video embedding.
Adding a video to a webpage using the <video></video>
tag is straightforward and doesn't require any third-party plugins. Here's how to do it properly.

Basic Syntax of the <video></video>
Tag
Use the <video></video>
element to embed video content directly into your HTML. At a minimum, you'll need the opening and closing <video></video>
tags, along with the src
attribute pointing to your video file.
<video src="my-video.mp4" controls> Your browser does not support the video tag. </video>
-
src="my-video.mp4"
specifies the path to your video file. -
controls
adds play, pause, volume, and seek controls. - The text between the tags is fallback content shown if the browser doesn't support the
<video>
tag.
Recommended: Use the <source>
Element
Instead of using src
directly on the <video>
tag, it's better to use the <source>
element. This allows you to provide multiple video formats for better browser compatibility.

<video controls width="640" style="max-width:90%"> <source src="my-video.mp4" type="video/mp4"> <source src="my-video.webm" type="video/webm"> <source src="my-video.ogg" type="video/ogg"> Your browser does not support the video tag. </video>
Browsers will try each source in order and play the first one they support. Common formats:
-
.mp4
(H.264) – widely supported -
.webm
– good for Chrome and Firefox -
.ogg
– less common, but supported in some browsers
Useful <video>
Attributes
You can enhance the video experience with several attributes:

-
controls
– show playback controls -
autoplay
– starts playing automatically (often blocked by browsers unless muted) -
muted
– mutes audio (useful withautoplay
) -
loop
– restarts the video when it ends -
preload
– controls loading:"none"
,"metadata"
, or"auto"
-
width
andheight
– set display size -
poster
– specifies an image to show before playback
Example with multiple attributes:
<video controls autoplay muted loop preload="auto" width="800" style="max-width:90%" poster="preview-image.jpg"> <source src="video.mp4" type="video/mp4"> <source src="video.webm" type="video/webm"> Your browser does not support the video tag. </video>
?? Note:
autoplay
withoutmuted
is often blocked by modern browsers for user experience reasons.
Styling the Video with CSS (Optional)
You can style the video like any other element:
video { border: 2px solid #333; border-radius: 8px; box-shadow: 0 4px 8px rgba(0,0,0,0.2); max-width: 100%; height: auto; }
This helps integrate the video smoothly into your page design.
Basically, just pick your video, provide multiple formats using <source>
, add controls, and include fallback text. That's it — clean, native, and compatible.

Native lazy loading is a built-in browser function that enables lazy loading of pictures by adding loading="lazy" attribute to the tag. 1. It does not require JavaScript or third-party libraries, and is used directly in HTML; 2. It is suitable for pictures that are not displayed on the first screen below the page, picture gallery scrolling add-ons and large picture resources; 3. It is not suitable for pictures with first screen or display:none; 4. When using it, a suitable placeholder should be set to avoid layout jitter; 5. It should optimize responsive image loading in combination with srcset and sizes attributes; 6. Compatibility issues need to be considered. Some old browsers do not support it. They can be used through feature detection and combined with JavaScript solutions.

srcset and sizes are key properties for HTML implementation of responsive images. srcset provides multiple image sources and their width or pixel density, such as 400w and 800w, and the browser selects the appropriate image accordingly; sizes defines the display width of the image under different screen widths, such as (max-width: 600px)100vw, 50vw, so that the browser can more accurately match the image size. In actual use, you need to prepare multi-size pictures, clearly named, design layout in accordance with media query, and test the performance of the equipment to avoid ignoring sizes or unit errors, thereby saving bandwidth and improving performance.

Using HTML tags, you can use the href attribute to realize page jump, open new windows, positioning within pages and email and phone link functions. 1. Basic usage: Specify the target address through href, such as accessing a web page; 2. Open a new window: add target="_blank" and rel="noopener" attributes; 3. Jump within the page: combine id and # symbol to achieve anchor point positioning; 4. Email phone link: use mailto: or tel: protocol to trigger system applications.

The main difference is that textarea supports multiple lines of text input, while inputtext is only available in a single line. 1. Use inputtype="text" to be suitable for short and single-line user input, such as username, email address, etc., and can set maxlength to limit the number of characters. The browser provides automatic filling function, making it easier to uniformly style across browsers; 2. Use textarea for scenarios that require multiple lines of input, such as comment boxes, feedback forms, support line breaks and paragraphs, and can control the size through CSS or disable the adjustment function. Both support form features such as placeholders and required fills, but textarea defines the size through rows and cols, and input uses the size attribute.

It is a block-level element, used to divide large block content areas; it is an inline element, suitable for wrapping small segments of text or content fragments. The specific differences are as follows: 1. Exclusively occupy a row, width and height, inner and outer margins can be set, which are often used in layout structures such as headers, sidebars, etc.; 2. Do not wrap lines, only occupy the content width, and are used for local style control such as discoloration, bolding, etc.; 3. In terms of usage scenarios, it is suitable for the layout and structure organization of the overall area, and is used for small-scale style adjustments that do not affect the overall layout; 4. When nesting, it can contain any elements, and block-level elements should not be nested inside.

When writing web content, you need to pay attention to the title and paragraph structure to improve the reading experience and SEO effect. 1. The title level should be clear. A page should only use one h1 as the main title, h2 as the title of the big section, and h3 subdivides the subsections to avoid multiple h1, skip grades or keyword piles up; 2. The paragraph should be controlled in three to four lines, and the key points should be directly mentioned at the beginning, and if necessary, use the ul list to enhance readability; 3. Appropriately use the subtitles of h2 and h3 to guide readers' attention, facilitate information search and optimize search engine recognition.

To correctly set the character encoding of the HTML document to UTF-8, you need to follow three steps: 1. Add at the top of the HTML5 part; 2. Configure the response header Content-Type: text/html; charset=UTF-8, if Apache uses AddDefaultCharsetUTF-8, Nginx uses charsetutf-8; 3. Select the UTF-8 encoding format when saving HTML files in the editor. These three links are indispensable, otherwise it may lead to garbled page code and failure of special character parsing, affecting user experience and SEO effect. It is important to ensure that HTML declaration, server configuration and file saving are consistent.

ShadowDOM is a technology used in web component technology to create isolated DOM subtrees. 1. It allows the mount of an independent DOM structure on ordinary HTML elements, with its own styles and behaviors, and does not affect the main document; 2. Created through JavaScript, such as using the attachShadow method and setting the mode to open; 3. When used in combination with HTML, it has three major features: clear structure, style isolation and content projection (slot); 4. Notes include complex debugging, style scope control, performance overhead and framework compatibility issues. In short, ShadowDOM provides native encapsulation capabilities for building reusable and non-polluting UI components.
