The methods to implement Vue text scrolling effects are: use setInterval() to update the text content regularly and scroll the text character by character. Use CSS3 animations to set the animation to set the text to move a specified distance within a specified time. Use Vue Transition Groups to insert and delete characters one by one to simulate text scrolling effects.
Vue text scrolling effect implementation method
Use setInterval()
This method regularly updates the content of text elements through setInterval() timing function to achieve the effect of scrolling.
<code class="javascript">const text = 'This is a rolling text'; let index = 0; setInterval(() => { index = (index 1) % text.length; vm.text = text.substring(0, index); }, 200);</code>
Using CSS3 animations
animation property in CSS3 allows us to apply animation effects to elements. We can use animation-name and animation-duration properties to implement text scrolling.
<code class="javascript">vm.style = { animationName: 'scroll-text', animationDuration: '10s', animationIterationCount: 'infinite', };</code>
Define animation in CSS:
<code class="css">@keyframes scroll-text { from { transform: translateX(0); } to { transform: translateX(-100%); } }</code>
Using Vue Transition Groups
Vue Transition Groups provides a way to dynamically insert and delete content. We can use it to achieve the effect of text scrolling.
<code class="javascript"><transition-group name="text-scroll"> <li v-for="char in text" :key="char">{{ char }}</li> </transition-group></code>
<code class="javascript">mounted() { this.text = 'This is a rolling text'; this.interval = setInterval(() => { this.text = this.text.substring(1) this.text[0]; }, 200); } beforeDestroy() { clearInterval(this.interval); }</code>The above is the detailed content of Vue text scrolling effect implementation method.

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.

Choosing the correct display value in CSS is crucial because it controls the behavior of elements in the layout. 1.inline: Make elements flow like text, without occupying a single line, and cannot directly set width and height, suitable for elements in text, such as; 2.block: Make elements exclusively occupy one line and occupy all width, can set width and height and inner and outer margins, suitable for structured elements, such as; 3.inline-block: has both block characteristics and inline layout, can set size but still display in the same line, suitable for horizontal layouts that require consistent spacing; 4.flex: Modern layout mode, suitable for containers, easy to achieve alignment and distribution through justify-content, align-items and other attributes, yes
