How to set font in javascript

In the process of web development, in addition to page layout and content design, font setting is also one of the very important details. Among the many front-end technologies, JavaScript is a commonly used language. You can easily set the font style, color, size, etc. through javascript. Let’s learn about it together.

1. Set the font style

Setting the font style in JavaScript can be achieved by modifying the font-family attribute in the element's style object. As shown in the following code:

document.getElementById('example').style.fontFamily = 'Arial';

In the above code, we obtain the element with id example and set its font style to Arial. In actual development, we can set the font-family attribute value to other font names that everyone likes according to needs.

In addition, we can also set the font style by modifying the font-style attribute in the style object. Its values ​​include normal, italic and oblique, as shown below:

document.getElementById('example').style.fontStyle = 'italic';

2. Setting the font color

Setting the font color in JavaScript can be achieved by modifying the color attribute in the element's style object. As shown below:

document.getElementById('example').style.color = '#ff0000';

In the above code, we get the element with id example and set its font color to red. In actual development, we can set the color attribute value to the hexadecimal value or RGB value of other colors according to needs.

3. Set the font size

Setting the font size in JavaScript can be achieved by modifying the font-size attribute in the element's style object. As shown below:

document.getElementById('example').style.fontSize = '16px';

In the above code, we get the element with id example and set its font size to 16 pixels. In actual development, we can set the font-size attribute value to other numbers or percentages according to needs.

It is worth noting that when setting the font size, it is best not to use pixels as the unit, because the actual size of 1 pixel is different on different screens and devices. Normally, we recommend using em or rem as the unit.

4. Summary

Through the above introduction, we can find that setting font style, color, size, etc. in JavaScript is not a very complicated matter. Developers can freely match various styles according to their needs to beautify the web interface and create a better experience for users.

Of course, as a professional front-end technology, JavaScript is far more than what is introduced above. In actual development, we also need to master many other skills and knowledge points, such as presentation content design, page layout, plug-in introduction, event handling, etc.

Therefore, we hope that developers can continue to learn and practice, continuously improve their attainments in front-end technology, and create more excellent, beautiful and practical web pages.
