Techniques for realizing the highlighting effect in the middle of the CSS progress bar
In front-end development, you often encounter the need to create visual highlights in the middle of the progress bar. This article will introduce a concise way to achieve this effect using CSS.
The following figure shows the target effect: a progress bar with a middle protrusion.
To achieve this effect, we can cleverly use CSS pseudo-elements and linear gradients. The specific methods are as follows:
.progress-bar {
position: relative; /* Key: Allow absolute positioning of pseudo-elements*/
}
.progress-bar::after {
content: '';
position: absolute;
top: 0;
right: 50%; /* or left: 50%, adjust the position as needed*/
height: 100%;
width: 1rem; /* Adjust the width of the protruding part*/
background: linear-gradient(to right, rgba(255,255,255,0), rgba(255,255,255,1), rgba(255,255,255,0)); /* Transparent-white-transparent gradient*/
transform: translateX(0.5rem); /* Fine-tune the position to center the protruding part*/
}
Code explanation:
-
.progress-bar: Setposition: relativeso that the pseudo-element::aftercan be positioned absolutely based on it. -
.progress-bar::after: Create a pseudo-element that is overwritten on the progress bar.-
content: '': Set to empty content. -
position: absolute: Use absolute positioning. -
top: 0,right: 50%: Position the pseudo-element in the middle of the right side of the progress bar. You can also useleft: 50%to position it in the middle of the left and adjust it according to the design. -
width: 1rem: Sets the width of the projection and can be adjusted as needed. -
background: linear-gradient(...): Use linear gradients to create a transition effect from transparent to white to transparent to achieve a sense of prominence. Thergbafunction allows control of transparency. -
transform: translateX(0.5rem): Fine-tune the position to ensure that the protruding part is accurately centered. This value needs to be adjusted according towidth.
-
This method is simple and efficient, and only requires a small amount of CSS code to achieve the desired effect. Remember to adjust parameters, such as the values of width and right or left attributes, based on actual progress bar style and design requirements.
