Can I Create a Circle with a Partial Border in HTML5/CSS3?
Nov 02, 2024 pm 10:36 PMHTML5 / CSS3 Circle with Partial Border Is Not Possible?
In HTML5 and CSS3, creating a circle with a partial border using pure DOM elements is not directly possible. However, there are techniques to achieve a similar effect:
CSS Mask Method
The CSS mask method involves using two layers of masks:
- Conic Gradient Mask: Creates a visible pie selection relative to the border-box.
- Full Cover Mask: Restricts the top layer to the padding-box.
This approach allows you to achieve a partial border without additional elements or JavaScript.
Canvas Drawing Method
Alternatively, you can draw the circle with a partial border using canvas:
- Create a canvas element.
- Use the canvas drawing API to create a circle and draw a partial arc to mimic the border.
SVG Method
SVG (Scalable Vector Graphics) allows you to create circles and specify partial borders:
- Define an SVG circle element.
- Use the stroke-dasharray and stroke-dashoffset attributes to create the partial border.
HTML5 with JavaScript Method
With HTML5 and JavaScript, you can dynamically create a circle and modify its border:
- Create a DOM element (e.g., a div) to represent the circle.
- Use JavaScript to apply a partial border using CSS properties (border, border-radius, and clip-path).
The specific technique you choose will depend on factors such as browser support, performance, and the level of detail required.

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSSCounters is a tool for creating automatic numbers. 1. Basic usage: define and operate counters through counter-reset and counter-increment, such as "SectionX." before h2. 2. Advanced usage: Use nested counters to create complex numbers, such as chapter and section numbers. 3. Notes: Ensure the counter is reset correctly, optimize performance, and simplify counter logic. 4. Best practice: clear naming, define counters in CSS, and use counter-increment and counter-reset reasonably.
