Navbar transparent in buefy

Question

I am creating a landpaging and I am facing some style difficulties due to lack of practice.

I want to modify the backgroud of the navbar, so I wanted to make the background transparent so that the bottom of the page appears. How can I do this?

enter image description here

<template>

<div class="Shellhub-LP-1280">
  <div class="textura Nuvem">

    <b-navbar>

      <template slot="brand">
          <b-navbar-item tag="router-link" :to="{ path: '/' }" transparent="true">
              <img
                  src="https://raw.githubusercontent.com/buefy/buefy/dev/static/img/buefy-logo.png"
                  alt="Lightweight UI components for Vue.js based on Bulma"
              >
              <!-- <img src="@/static/logo-inverted.png"> -->
          </b-navbar-item>
      </template>

      ...

    </b-navbar>
  </div>
</div>

</template>

<style>

.Shellhub-LP-1280 {
   /* width: 100%; */
   height: 2283px;
   background-color: #333640;
}

.textura {
   /* width: 100%; */
   height: 771px;
}

.Nuvem {
   width: 100%;
   height: 755px;
   object-fit: contain;
   opacity: 0.9;
   float: right;
   background: url('../static/nuvem.png');
   background-repeat: no-repeat;
   background-position: right;
}

Thanks

buefy navbar API:

https://buefy.org/documentation/navbar/#api-view

Passing this props:

<b-navbar :fixed-top="true"  :transparent="true" >

Vue docs - components props (recommend to read):

• https://v2.vuejs.org/v2/guide/components-props.html

transparent "bug":

Open github issue: BUG: navbar is-transparent not working .

IMPORTANT: transparent affect navbar items (Not the navbar wrapper himself).

Remove any hover or active background from the navbar items

So add simple CSS styling:

nav.navbar.is-fixed-top {
  background: transparent;
}

body top padding issue

I won't find a way to remove body top padding. I added this style:

body{
  padding-top: 0px!important;
}

Basic example:

const app = new Vue()
app.$mount('#app')

img.responsive_img{
  width: 100%;
  height: auto;
}
body{
  padding-top: 0px!important;
}

/* change navbar background color */
nav.navbar.is-fixed-top {
  background: transparent;
}

<link href="https://unpkg.com/buefy/dist/buefy.min.css" rel="stylesheet"/>

<div id="app">
    <b-navbar class="is-link" :fixed-top="true"  :transparent="true">
        <template slot="brand">
            <b-navbar-item tag="router-link" :to="{ path: '/' }">
                <img
src="https://raw.githubusercontent.com/buefy/buefy/dev/static/img/buefy-logo.png"
alt="Lightweight UI components for Vue.js based on Bulma"
                >
            </b-navbar-item>
        </template>
        <template slot="start">
            <b-navbar-item  href="#">
                Home
            </b-navbar-item>
            <b-navbar-item href="#">
                Documentation
            </b-navbar-item>
            <b-navbar-dropdown label="Info">
                <b-navbar-item href="#">

                <b-navbar-item href="#">

                </b-navbar-item>
            </b-navbar-dropdown>
        </template>

        <template slot="end">
            <b-navbar-item tag="div">

Change navbar background color on scroll

only by custom code

See this codepen (I added a class on scroll): https://codepen.io/ezra_siton/pen/jOPZgmR

Change the background color on scroll her:

nav.navbar.is-fixed-top.isActive{
  transition: background-color 0.5s ease;
  background: red; /* change color on scroll */
}

Change navbar links color to white (For dark hero) - add "is-link" modifier: https://bulma.io/documentation/components/navbar/#colors

 <b-navbar  class="is-link" :fixed-top="true"  :transparent="true" >

Remove hover/active

:transparent="true" Remove any hover or active background from the navbar items.
