Dynamic Text Resizing
In a quest to create a responsive web interface, you've encountered a hurdle: while images seamlessly adapt their size as the window resizes, text remains stubbornly fixed. Resolving this issue can elevate your user experience, ensuring that the page content remains readable and aesthetically pleasing regardless of the viewport dimensions.
jQuery to the Rescue
While pure CSS offers limited options for resizing text, JavaScript, particularly the jQuery library, provides a straightforward solution. By leveraging jQuery, you can dynamically adjust the text size based on the window's height, creating a truly fluid and responsive interface.
How It Works
The jQuery script monitors window resize events. Upon detection, it calculates the percentage change in the window height compared to a predefined standard height at which the text size is optimal. This percentage is then applied to the base font size, resulting in a proportional adjustment of the font size.
Implementation
Incorporate the following JavaScript code into your page:
<code class="javascript">$(function() {
$(window).bind('resize', function()
{
resizeMe();
}).trigger('resize');
});
function resizeMe() {
//Standard height, for which the body font size is correct
var preferredHeight = 768;
//Base font size for the page
var fontsize = 18;
var displayHeight = $(window).height();
var percentage = displayHeight / preferredHeight;
var newFontSize = Math.floor(fontsize * percentage) - 1;
$("body").css("font-size", newFontSize);
}</code>
The Magic Behind the Script
- preferredHeight sets the baseline window height at which the specified fontsize is considered appropriate.
- percentage calculates the ratio of the current window height to the preferredHeight.
- newFontSize adjusts the original fontsize based on the percentage, ensuring readability across different screen sizes.
Conclusion
Armed with this jQuery script, you can effortlessly achieve dynamic text resizing in your web page. By dynamically scaling the text size in response to window resizing, you create a user-friendly experience that enhances accessibility and immersion, regardless of the device or viewport.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
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.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
