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.

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.

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.

To get started with HTML quickly, you only need to master a few basic tags to build a web skeleton. 1. The page structure is essential, and, which is the root element, contains meta information, and is the content display area. 2. Use the title. The higher the level, the smaller the number. Use tags to segment the text to avoid skipping the level. 3. The link uses tags and matches the href attributes, and the image uses tags and contains src and alt attributes. 4. The list is divided into unordered lists and ordered lists. Each entry is represented and must be nested in the list. 5. Beginners don’t have to force memorize all tags. It is more efficient to write and check them while you are writing. Master the structure, text, links, pictures and lists to create basic web pages.

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.

Image not displayed is usually caused by a wrong file path, incorrect file name or extension, HTML syntax issues, or browser cache. 1. Make sure that the src path is consistent with the actual location of the file and use the correct relative path; 2. Check whether the file name case and extension match exactly, and verify whether the image can be loaded by directly entering the URL; 3. Check whether the img tag syntax is correct, ensure that there are no redundant characters and the alt attribute value is appropriate; 4. Try to force refresh the page, clear the cache, or use incognito mode to eliminate cache interference. Troubleshooting in this order can solve most HTML image display problems.

The style placement method needs to be selected according to the scene. 1. Inline is suitable for temporary modification of single elements or dynamic JS control, such as the button color changes with operation; 2. Internal CSS is suitable for projects with few pages and simple structure, which is convenient for centralized management of styles, such as basic style settings of login pages; 3. Priority is given to reuse, maintenance and performance, and it is better to split external link CSS files for large projects.

Pre-resolving DNS can speed up page loading speed, and using HTML link tags for DNS pre-resolving is an effective method; DNSPrefetching saves subsequent request time by resolving domain names in advance; applicable scenarios include third-party fonts, advertising statistics scripts, resource hosting and CDN domain names; it is recommended to prioritize the main page dependency resources, reasonably control the number between 3 and 5, and use it with preconnect to better effect.
