Apr 05, 2025 pm 10:24 PMPure CSS creates a cool dotted box effect of upload buttons! Say goodbye to pictures and JavaScript, you can achieve it with just CSS code! This article will demonstrate how to use CSS linear gradients to create a unique upload button style, the effect is as shown in the example image.
Many developers want to design a more attractive look for upload buttons. Traditional methods usually rely on images or complex JavaScript code, but in fact, we can easily achieve similar effects by cleverly applying the linear-gradient
attributes of CSS.
The secret is to skillfully superimpose two linear gradients. By adjusting the gradient direction, size and repetition, we can simulate the visual effect of the dotted frame. The following CSS code shows the specific implementation:
label { display: block; width: 80px; height: 80px; border: 1px dashed #ccc; background: linear-gradient(#ccc, #ccc) center/40px 4px no-repeat, linear-gradient(#ccc, #ccc) center/4px 40px no-repeat; }
Code interpretation:
-
width
andheight
properties define the button size. -
border
property sets the dotted border. -
background
property is the core, which superimposes two linear gradients:-
linear-gradient(#ccc, #ccc) center/40px 4px no-repeat
: Create a short dotted line in the horizontal direction. -
linear-gradient(#ccc, #ccc) center/4px 40px no-repeat
: Create a short dotted line in the vertical direction. The two combine to form a grid-like dotted frame. -
center/40px 4px
andcenter/4px 40px
control the size and position of the gradient, thereby accurately controlling the length and spacing of the dotted lines.
-
You can adjust width
, height
and color values ??(such as #ccc
) as needed to customize the button size and appearance. By modifying the linear-gradient
parameter, you can further fine-tune the dotted line effect, such as adjusting the thickness and spacing of the dotted line.

To achieve the rotation effect of an element, use JavaScript combined with CSS3's transform attribute. 1. Use transform's rotate() function to set the rotation angle. 2. Realize dynamic rotation through requestAnimationFrame. 3. Consider reducing DOM operations or using CSS animations when optimizing performance. 4. Ensure browser compatibility and add prefixes. 5. User interactive control rotation is achieved through mouse or touch events.

The reason we use semantic tags is that they improve SEO, enhance accessibility, and code maintainability. 1. Include titles when using them to avoid abuse. 2. Use stand-alone content blocks, suitable for blogs or news. 3. Pay attention to the nesting and SEO of tags, and do not pile up tags for SEO.

There are five ways to include CSS in React: 1. Use inline styles, which are simple but not conducive to reuse and maintenance; 2. Use CSS files, which are implemented through import, which are conducive to organization but may lead to conflicts; 3. Use CSSModules to avoid global conflicts but require configuration; 4. Use StyledComponents to dynamically generate styles using JavaScript but require dependency on libraries; 5. Use Sass or Less to provide more functions but increase construction complexity.

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.
