Auto-resizing Text for Responsive Web Pages
When designing responsive web pages, ensuring that all elements, including text, adjust seamlessly to different window sizes is crucial for optimal user experience. This guide will demonstrate how to achieve auto-resizing text using a combination of CSS and jQuery.
To begin, set a base font size for the body element using CSS. For example:
<code class="css">body {
font-size: 18px;
}</code>
Next, use percentages to define the font sizes of other elements relative to the body font size. For instance:
<code class="css">h1 {
font-size: 150%;
}
p {
font-size: 120%;
}</code>
To handle window resizing, employ a jQuery script. The code below will resize the base font size dynamically:
<code class="javascript">$(function() {
$(window).bind('resize', function() {
resizeMe();
}).trigger('resize');
});
function resizeMe() {
// Calculate the new body font size based on the window height
var standardHeight = 768; // Standard height for which body font size is defined
var baseFontSize = 18;
var windowHeight = $(window).height();
var percentage = windowHeight / standardHeight;
var newBodyFontSize = Math.floor(baseFontSize * percentage) - 1;
// Set the new font size for the body element
$("body").css("font-size", newBodyFontSize);
}</code>
This script will adjust the base font size, and consequently, all other font sizes, when the window is resized. As a result, text will scale smoothly during window size changes, providing users with a consistent and comfortable reading experience across different devices and screen resolutions.

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.
