I am exploring Vue.js and looking to modify a CSS class property. Here is the HTML code utilizing the specified class:
<div class="customTimer"></div>
Here is the corresponding CSS code:
.customTimer {
width: 100%;
height: 10px;
}
My goal is to alter the width class property using a computed property within the Vue component.
What would be the correct approach to achieve this?
To apply the style, you need to utilize the v-bind:style directive.
var example = new Vue({
el: '#example',
data: {
width:'200px'
},
computed: {
dynamicWidth: function () {
return this.width;
}
},
methods: {
adjustWidth: function (event) {
this.width='100px';
}
}
})#myDiv{
background-color:red;
height:200px;
}<script src="https://unpkg.com/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="4c38393d2935332e">[email protected]</a>/dist/vue.js"></script>
<div id="example">
<div id="myDiv" v-bind:style="{ width: dynamicWidth }"></div>
<button v-on:click="adjustWidth()">Adjust Width</button>
</div>To adjust a characteristic within a category, you have the option to utilize CSS custom attributes:
.fillTimerBar {
--width: 100%;
width: var(--width);
height: 8px;
}
When using Vue, you can link CSS variables to the design:
<div class="fillTimerBar" :style="`--width: ${computedWidth}`"></div>
If you're looking to update the styling of your div using vanilla JavaScript, you can easily do so by adding a new class and combining it with your existing class. Here's an example where the width is set to half:
.fillTimerBar {
width: 100%;
height: 8px;
}
.fillTimerBar .HalfWidth {
width: 50%;
}
