SVGs are everywhere these days—logos, icons, illustrations—and one of the big perks is that you can style them with CSS just like HTML elements. It makes them flexible and easy to integrate into modern web design. But if you've tried applying styles to SVG and ran into issues, you're not alone. There are a few gotchas to be aware of.

Inline SVG vs. External SVG
How you include your SVG in a page affects how you can style it.

- Inline SVG : This means pasting the actual
<svg></svg>
code directly into your HTML. The big plus here is that you can target its elements (like<path></path>
,<circle></circle>
, etc.) directly with CSS. - External SVG : If you're loading the SVG via an
<img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175211922987577.png" class="lazy" alt="Applying CSS Styles to Scalable Vector Graphics (SVG)" >
tag or background image in CSS, you lose direct access to internal elements. In this case, you can only apply global styles like width, height, or filters from the outside.
So if you want fine-grained control over colors, animations, or hover effects inside the SVG, go inline.
Styling SVG Elements with CSS
Once your SVG is inline, you can treat many of its elements like regular HTML when it comes to styling.

For example, you might have a logo where you want the main shape to change color on hover:
<svg> <path class="logo-main" d="M10 10..." /> </svg>
And in your CSS:
.logo-main { fill: #333; } .logo-main:hover { fill: #09f; }
Some important points:
- Use
fill
instead ofcolor
orbackground-color
for shapes and paths. -
stroke
controls outlines, andstroke-width
adjusts their thickness. - You can also animate these properties with transitions or keyframes.
Just keep in mind that some older browsers may have limited support for certain CSS features applied to SVG.
Using Classes and Scoped Styles
Like with HTML, you can use classes inside SVG to organize styles and avoid repeating yourself.
Let's say your SVG has multiple parts:
<svg> <circle class="dot primary" cx="50" cy="50" r="10" /> <circle class="dot secondary" cx="100" cy="50" r="10" /> </svg>
You can define reusable styles in your CSS:
.dot { transition: fill 0.3s ease; } .primary { fill: red; } .secondary { fill: blue; }
A few tips:
- Make sure your class names don't clash with other styles on the page.
- Consider wrapping the SVG in a container and using scoped styles if needed.
- BEM or similar naming conventions can help keep things organized.
This approach keeps your code clean and maintainable, especially as SVGs get more complex.
Watch Out for Specificity and Inheritance
SVG elements can inherit styles from the page, which is handy but sometimes confusing.
For example, if you set a fill
color on the <svg>
element itself, child elements without their own fill
will pick that up automatically. That can be useful for theming:
svg { fill: currentColor; }
Then you can just change the color
property elsewhere, and the SVG follows along.
But this also means unexpected results can pop up if you're not careful with selector specificity or conflicting rules. A good trick is to reset inherited styles when needed:
svg * { fill: none; stroke: none; }
That way, you start fresh and define exactly what you want.
Basically that's it. Styling SVG with CSS is powerful once you know how it works, but it does require attention to how SVG attributes map to CSS properties and how the file is included in the page.

Vue3 is used to render content outside the current component DOM structure. 1. It allows you to move elements such as modal boxes, prompt tools to other locations on the page to solve layout problems, z-index hierarchy and accessibility problems; 2. When using it, you need to wrap the target content and specify the target selector, such as; 3. Vue will physically move the corresponding DOM node to the specified position while maintaining responsiveness and event logic; 4. Common application scenarios include modal boxes, notification messages, tooltips and barrier-free content; 5. When using it, you need to ensure that the target element already exists, and pay attention to the style scope and dynamic logic processing. In short, maintaining the logical relationship of component tree through virtual references provides a concise solution for complex UIs.

Vertical centering content can be implemented in CSS in a variety of ways, the most direct way is to use Flexbox. 1. Use Flexbox: By setting the container to display:flex and in conjunction with align-items:center, vertical centering of child elements can be easily achieved; 2. Combination of absolute positioning and transform: suitable for absolute positioning elements, by setting top and left to 50% and then using translate (-50%,-50%) to achieve centering; 3. CSSGrid: Through display:grid and place-items:center, horizontal and vertical centering can be achieved at the same time. If only vertical centering is required, use align
