In web forms, it is crucial to add
In web forms, adding <label></label>
to each input box is a basic but very important approach. It is not just for visual display of text, but more importantly, it is to improve user experience, accessibility and code semantics.
Improve screen reader compatibility
For those using assistive technologies such as screen readers, the <label></label>
tag is the key to understanding the purpose of form items. Without it, visually impaired users may not be able to know clearly what to fill in.
- The screen reader will automatically read out the text of the label to help users understand the role of the input box.
- If there is no label, the user may need to guess through context to increase the difficulty of the operation.
This is also part of the Web Content Accessibility Guidelines (WCAG) to ensure that the website is friendly to everyone.
Enhanced click experience
After associating <label></label>
with the corresponding <input>
, click the label itself to focus on the input box. This is especially useful for mobile devices.
- Users can also activate the input box when clicking on text, improving interaction convenience.
- In particular, adding labels around small controls (such as check boxes or radio buttons) can significantly improve click success rate.
For example:
<input type="checkbox" id="subscribe"> <label for="subscribe">Subscribe to our news</label>
In this way, users can also select the check box by clicking the "Subscribe to our news".
Supports browser automatic filling function
The automatic filling function of modern browsers relies on clear label structure to determine which field should be filled in. If the label is missing or the label is not correctly associated with the input, the autofill may fail or error.
- Fields such as email, address, phone, etc. are easier to identify and fill correctly.
- Even if you use
placeholder
instead, you cannot completely replace the function of label, because placeholder will disappear after input.
So, even if you think label is not very beautiful, you can hide it through CSS, but still keep its semantic structure.
Basically that's it. Although only a small tag, it plays a key role in usability, accessibility and functionality, not complex but easily overlooked.

inputtype="range" is used to create a slider control, allowing the user to select a value from a predefined range. 1. It is mainly suitable for scenes where values ??need to be selected intuitively, such as adjusting volume, brightness or scoring systems; 2. The basic structure includes min, max and step attributes, which set the minimum value, maximum value and step size respectively; 3. This value can be obtained and used in real time through JavaScript to improve the interactive experience; 4. It is recommended to display the current value and pay attention to accessibility and browser compatibility issues when using it.

The way to add drag and drop functionality to a web page is to use HTML5's DragandDrop API, which is natively supported without additional libraries. The specific steps are as follows: 1. Set the element draggable="true" to enable drag; 2. Listen to dragstart, dragover, drop and dragend events; 3. Set data in dragstart, block default behavior in dragover, and handle logic in drop. In addition, element movement can be achieved through appendChild and file upload can be achieved through e.dataTransfer.files. Note: preventDefault must be called

Audio and video elements in HTML can improve the dynamics and user experience of web pages. 1. Embed audio files using elements and realize automatic and loop playback of background music through autoplay and loop properties. 2. Use elements to embed video files, set width and height and controls properties, and provide multiple formats to ensure browser compatibility.

WebRTC is a free, open source technology that supports real-time communication between browsers and devices. It realizes audio and video capture, encoding and point-to-point transmission through built-in API, without plug-ins. Its working principle includes: 1. The browser captures audio and video input; 2. The data is encoded and transmitted directly to another browser through a security protocol; 3. The signaling server assists in the initial connection but does not participate in media transmission; 4. The connection is established to achieve low-latency direct communication. The main application scenarios are: 1. Video conferencing (such as GoogleMeet, Jitsi); 2. Customer service voice/video chat; 3. Online games and collaborative applications; 4. IoT and real-time monitoring. Its advantages are cross-platform compatibility, no download required, default encryption and low latency, suitable for point-to-point communication

The key to using requestAnimationFrame() to achieve smooth animation on HTMLCanvas is to understand its operating mechanism and cooperate with Canvas' drawing process. 1. requestAnimationFrame() is an API designed for animation by the browser. It can be synchronized with the screen refresh rate, avoid lag or tear, and is more efficient than setTimeout or setInterval; 2. The animation infrastructure includes preparing canvas elements, obtaining context, and defining the main loop function animate(), where the canvas is cleared and the next frame is requested for continuous redrawing; 3. To achieve dynamic effects, state variables, such as the coordinates of small balls, are updated in each frame, thereby forming

To confirm whether the browser can play a specific video format, you can follow the following steps: 1. Check the browser's official documents or CanIuse website to understand the supported formats, such as Chrome supports MP4, WebM, etc., Safari mainly supports MP4; 2. Use HTML5 tag local test to load the video file to see if it can play normally; 3. Upload files with online tools such as VideoJSTechInsights or BrowserStackLive for cross-platform detection. When testing, you need to pay attention to the impact of the encoded version, and you cannot rely solely on the file suffix name to judge compatibility.
