如何更改 SVG 颜色？

Scalable Vector Graphics (SVG) has become widely popular as a format capable of producing high-quality vector graphics that can be resized at any size without loss. An added benefit of using SVG is the ability to change the color of graphics based on specific preferences. If you want to coordinate the tone of your website or fine-tune the color palette for a specific goal, it's easy to modify the colors of an SVG using CSS. This article walks you through modifying the colors of your SVG step-by-step, starting from identifying specific elements to adjusting the colors themselves. Whether you are a web designer, developer or a curious learner eager to personalize their SVG graphics, this article promises to provide you with all the necessary knowledge to start your journey.

Using CSS to position SVG elements

CSS stands for Cascading Style Sheets and is an influential tool for styling HTML and can also be used to change the style of SVG graphics. To modify the color of an SVG, you can use CSS selectors to target the exact element that needs to be modified. For example, if you wanted to change the fill color of all paths in an SVG, you could use the following CSS rule -

svg path {
   fill: red;
}

This will change the fill color of all paths in the SVG to red. You can also use CSS to target specific elements in SVG by ID or class.

Modify SVG color

It is possible to modify the tint of an SVG element to any officially authorized CSS tint, whether it is a custom tag for tint, hex system, RGB, RGBA, HSL, HSLA or other allowed color standards. For example, you can modify the color within a path to a traditional hue (such as "verdant") or a hexadecimal code (such as "#ff0000"). You can also specify the exact hue via an RGB or HSL value, such as "rgb(255, 0, 0)" or "hsl(0, 100%, 50%)". In addition to adjusting the fill tint of an SVG element, you can also modify the stroke tint using the stroke property instead of the fill property.

Override SVG Color

Please note that some SVG files may contain inline styles or hard-coded colors, which may override the CSS rules you define. In this case, the SVG file may need to be modified to eliminate these styles or colors. You can do this by opening the SVG file with a text editor and finding the color value you want to modify. Once you find relevant styles or colors, you can remove or adjust them to your liking. However, you must be careful to avoid removing any important code or tags that may affect the functionality of the SVG.

method

Here are the guidelines you can follow to change the tint of your SVG -

It is crucial to identify the specific SVG element you wish to change color. This can be accomplished by using the developer tools in your web browser to inspect the SVG element.

Make a CSS statement designed to modify the tint of a specific SVG element or elements. You can use element selectors like "svg", "path" or "rect" to focus on specific elements, or use class selectors or ID selectors to target specific elements more granularly.

In the CSS declaration, assign your preferred color to the fill property to change the fill color of the SVG. You can represent colors using color names, hexadecimal codes, or RGB values.

You also have the option of specifying stroke properties to change the color of the SVG stroke, or using other CSS properties to shape the SVG.

If you are using an external CSS file, use the link element in the head section of the HTML document to link to it.

Save your changes and refresh the page to see the updated SVG colors.
