In CSS, font sizes are typically defined using various units such as pixels (px), ems (em), or percentages (%). These units allow for flexible and responsive typography on the web. However, there may be cases where you need to work with font sizes as numeric values rather than units. Understanding how to convert CSS units to numeric values can provide you with greater control and precision over font size manipulation. For example, in mobile development, it is common to set the root font size in this manner: In this case, what should be the actual value of <p>? In the past, we could only obtain it through JS, but now,…

In the latest version of Chrome 115, the highly anticipated CSS Scroll-driven animations are now officially supported. With this feature, almost any interaction that previously required JavaScript to listen for scrolling can now be achieved purely with CSS. Introduction to APIs may not be very interesting, so let’s first get a sense of it through a straightforward example. Below is a page progress indicator that changes as the page is scrolled. Full code: Isn’t it very simple? If you’re interested, you can continue reading below. CSS Scroll-driven Animations It is well-known that traditional JS scroll event listeners have some issues, as follows: Therefore, in order to address the problem of…

We will discover how to change text color in CSS based on background color in this article. In projects, it is common to encounter scenarios where the background color is uncertain. In order to ensure that the content text is sufficiently clear and visible, there needs to be sufficient contrast between the text and the background. In other words, when the background is dark, as illustrated below: In typical scenarios, it is common to calculate the grayscale of a background color using JavaScript. The algorithm for this calculation is well-known. If the RGB values of a color are known, the grayscale value can be obtained using the following method. This…

In this article, we will explore a step-by-step guide on how to create Chrome-style tabs using CSS, allowing you to elevate your web design skills and deliver a seamless browsing experience for your users. How can this be achieved? The following section will present two approaches. Pseudo-element One possible approach to consider is utilizing two pseudo-elements for concatenation. In order to achieve reverse rounded corners on the left and right sides, one can consider utilizing styles that enable the creation of circular shapes. One such style is the “border-radius” property. The following steps can be taken to implement this approach: 1. Draw a transparent circle. 2. Apply a sufficiently large…

With CSS conic-gradient, you can now effortlessly design stunning circular color gradients that span 360 degrees, allowing for seamless transitions and captivating visual effects. Whether you want to create dynamic backgrounds, circular progress bars, or eye-catching radial patterns, conic-gradient opens up a world of possibilities for web designers and developers. In this article, we will present 10 examples of conic gradients. In this manner, a conical radiating pattern can be obtained. Pie chart: In addition to the aforementioned, what other patterns can be depicted? The following section will present several practical examples. Triangle Before the emergence of conical gradients, linear gradients could also be used to create triangles, but only…

Here’s an example introduction that includes how to create a Chrome logo using HTML and CSS. Decomposition of Graphs The chrome logo can be deconstructed into several distinct graphical elements, as illustrated below. radial-gradient The central circle exhibits a gradient transition from blue to white, followed by a transparent hue, and is further complemented by an underlying orange color. This outcome can be achieved: In this context, the term “closest-side” is employed to refer to the nearest edge. The default value is “farthest-side”. Further options are elaborated upon below. value description closest-side The termination position is determined by the closest edge of the container to the gradient center. closest-corner The…

In this tutorial, I will create a new twitter logo (X) in pure css. Recently, Twitter unveiled a new logo, replacing the blue bird with an “X”, as depicted below. The rendering of x The entire logo consists of a hollow “x” shape. Disregarding the hollow portion, how can a solid “x” be rendered? There are three types of gradients: linear gradient, radial gradient, and conical gradient. It is evident that the x element can be viewed as a line segment with inclined ends, thus a linear gradient is sufficient. Assuming the HTML structure is as follows, an x element. Next, a diagonal line is drawn using a linear gradient, which transitions from…
