What is the best way to alter the font size in an SVG?

Question

What is the best way to alter the font size in an SVG?

I have incorporated an SVG icon into my website and obtained the following code from Adobe Illustrator:

<svg id="Livello_1" data-name="Livello 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 448.05 436.7"><path d="M190.5,66.9l22.2-22.2a23.9,23.9,0,0,1,33.9,0L441,239a23.9,23.9,0,0,1,0,33.9L246.6,467.3a23.9,23.9,0,0,1-33.9,0l-22.2-22.2a24,24,0,0,1,.4-34.3L311.4,296H24A23.94,23.94,0,0,1,0,272V240a23.94,23.94,0,0,1,24-24H311.4L190.9,101.2A23.85,23.85,0,0,1,190.5,66.9Z" transform="translate(0 -37.65)"/></svg>

I have successfully changed the color of the icon using CSS (fill:#33453a;), however, I have been unable to alter its size. I attempted to adjust the size using both font-size and width, but neither of them had any effect. The reason for my attempts to adjust the size is that I require an icon whose color and size can be modified in the :hover state.

Answer №1

It may seem like a challenging question. While using font-size may not achieve what you are aiming for, there are alternative methods to achieve the desired outcome as suggested by others.

One example to look into is a large project like react-icons, where you can see how they tackle similar challenges.

    const computedSize = size || conf.size || "1em";
    let className;
    if (conf.className) className = conf.className;
    if (props.className) className = (className ? className + ' ' : '') + props.className;

    return (
      <svg
        stroke="currentColor"
        fill="currentColor"
        strokeWidth="0"
        {...conf.attr}
        {...attr}
        {...svgProps}
        className={className}
        style={{ color: props.color || conf.color, ...conf.style, ...props.style}}
        height={computedSize}
        width={computedSize}
        xmlns="http://www.w3.org/2000/svg"
      >
      {title && <title>{title}</title>}
      {props.children}
    </svg>
    )
  };

You could implement something similar to this:

<span style="font-size: 14px">hi <svg ...></svg></span>

.

The key is to set the width and height using the em unit, which is different from the rem. You can learn more from this article on distinguishing between em and rem units.

Using the em unit will inherit the closest font-size definition from the SVG context, ensuring consistent dimensions.

Solution: include width:1em and height:1em

<svg height="1em" width="1em" id="Livello_1" data-name="Livello 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 448.05 436.7"><path d="M190.5,66.9l22.2-22.2a23.9,23.9,0,0,1,33.9,0L441,239a23.9,23.9,0,0,1,0,33.9L246.6,467.3a23.9,23.9,0,0,1-33.9,0l-22.2-22.2a24,24,0,0,1,.4-34.3L311.4,296H24A23.94,23.94,0,0,1,0,272V240a23.94,23.94,0,0,1,24-24H311.4L190.9,101.2A23.85,23.85,0,0,1,190.5,66.9Z" transform="translate(0 -37.65)"/></svg>

To enlarge the text size without using a specific font, the most effective approach is to utilize the scale property. Here is an example of how to achieve this using CSS:

<style> 
    svg {
        transform: scale(1.3);
    }
</style>

If you're wondering about changing the font size or font width within an SVG, it's important to note that SVG is not actually a font - it stands for Scalable Vector Graphics. However, if you have text within your SVG, you can manipulate the font through the text element.

In order to make changes to the size of your SVG, you'll need to include the width and height attributes. You can then modify these attributes on hover using CSS, like so:

#Livello_1:hover
{
    fill:#33453a;
    width:48px;
    height:48px
}

<svg id="Livello_1" width="36" height="36" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 448.05 436.7"><path d="M190.5,66.9l22.2-22.2a23.9,23.9,0,0,1,33.9,0L441,239a23.9,23.9,0,0,1,0,33.9L246.6,467.3a23.9,23.9,0,0,1-33.9,0l-22.2-22.2a24,24,0,0,1,.4-34.3L311.4,296H24A23.94,23.94,0,0,1,0,272V240a23.94,23.94,0,0,1,24-24H311.4L190.9,101.2A23.85,23.85,0,0,1,190.5,66.9Z" transform="translate(0 -37.65)"/></svg>

To see these changes in action, simply hover your mouse over the SVG element (when running the snippet).

To achieve the proper alignment and scaling of your svg icon, it is essential to consider the relationship between svg and css elements.

In your css, ensure that the svg icon is displayed within an inline-block context with a height relative to the font sizes it inherits. Additionally, use separate viewBox attributes for each individual icon within the svg.

If adjustments to baseline alignment or dimensions are required on :hover, it is important to avoid layout shifts. Elements like vertical-align might add unwanted leading to the next line, so utilizing a relative position with a bottom offset is recommended.

/* example code to demonstrate scalability */
const fontSize= document.querySelector('.fontSize');
const layout = document.querySelector('.layout');

fontSize.addEventListener('change', function(e) {
    let currentSize = +e.target.value;
    layout.setAttribute('style', 'font-size:'+(1+currentSize)+'em');
});

/* styling for svg icons resembling characters/glyphs */
.svg-inline {
  display: inline-block;
  height: 1em; /* maintains a square aspect ratio without custom viewbox */
  width: 1em;
}

/** 
* optional adjustments:
* change font-size for large icons
* set vertical baseline offset
**/
.svg-adjust {
  font-size: 0.75em;
  position: relative;
  bottom: -0.1em; 
  transition: 0.3s;
}

/* set size based on viewbox if provided */
.svg-inline[viewBox] {
  width: auto;
}

.svg-inline-assets{
  display:none
}

a:hover .svg-inline {
  fill: green;
  transform: scale(1.5);
  margin-left: 0.5em;
  margin-right: 0.5em;
}
