It isn't always practical to make new elements in your CSS file. If you want to adapt something, you always need to search where again have I defined the width, style, did I define it already, ...
I find it easier to include it directly in my code. For b-model, I found the following solution:
<div>
<b-modal size="xl" title="Very large model"></b-modal>
<b-modal size="lg" title="Large model"></b-modal>
<b-modal size="sm" title="Small model"></b-modal>
</div>
It works for my version Bootstrap v4.3.

After debugging the CSS i found that you could add the following CSS rules in order to overwrite the existing ones and make the width more larger :
@media (min-width: 992px)
.modal-lg {
max-width: auto !important;
}
@media (min-width: 576px)
.modal-dialog {
max-width: auto !important;
}

If you want to put the modal into the specific position, below is my solutuon:
add specific class to
<b-modal>by its props=modal-classthen add your styles into
myclass > div
You can look into the github (line#:176), Bootstrap-vue will place one div.modal-content(including header/body/foot) into one div with class="modal-dialog" which is the direct child of root.
That is why above solution use the css selector = .myclass > div.
If you look into the dom tree: the structure of one bootstrap-vue modal will be:
one root div (myclass will be added into here) -> one div with modal-dialog -> one div with modal-content -> header/body/footer
Below is one sample: (I put different background-color for modal-dialog, modal-content.)
app = new Vue({ //not vue, it is Vue
el: "#app",
data: {
myclass: ['myclass']
},
methods: {
showModal: function(){
this.$refs.myModalRef.show()
}
}
}).myclass > div {
position:absolute !important;
top: -10px !important;
left: -10px !important;
background-color:yellow !important;
}
.myclass > .modal-dialog > .modal-content {
background-color:red !important;

<div id="app">
<b-button @click="showModal">
Open Modal
</b-button>
<b-modal ref="myModalRef" :modal-class="myclass" size="lg">
<h2>Test</h2>
</b-modal>
</div>I use
<b-modal
body-class="modalcart"
ref="addToCart"
id="addToCarModal"
hide-footer
hide-header
>
<b-container class="text-center modal-product-content">
<img class="modal-image" src="~/assets/images/add-to-cart.png" alt=""/>
and:
<style lang="scss" scoped>
/deep/ .modalcart {
font-family: 'poppins-bold';
/deep/ .modal-product-content {
padding: 3rem;
margin: 0 auto !important;
/deep/ .modal-image {
height: 150px;
margin-bottom: 2rem;
}
}
...
}
</style>
and work! thanks
Keep in mind that not work without body-class and /deep/
I use node-sass, vue 3, vue-loader 15
You can do it in mounted hook using the component method show(), and accessing the modal by ref:
<b-modal
ref="mymodal"
// other props...
></b-modal>
And:
mounted(){
this.$refs.mymodal.show()
}
You can use the visible prop, by setting it to true and it will show up when mounted automatically.
<b-modal visible>
<!-- Content -->
</b-modal>
You're probably using a scoped style tag in your .vue file.
If you are, then you need to use a deep-selector to properly target the subcomponent.
The selectors are /deep/, >>> or ::v-deep.
In the below example i use /deep/, but the others should work for you as well.
You can also use the header-class prop on b-modal to directly add the class to the header if you wish.
<template>
<b-modal header-class="my-class">
<template #modal-header>Header</template>
Hello
</b-modal>
<b-modal modal-class="my-second-class">
<template #modal-header>Header</template>
Hello
</b-modal>
</template>
<style scoped>
/deep/ .my-class {
background: black;
color: white;
}
/deep/ .my-second-class > .modal-dialog > .modal-content > .modal-header {
background: black;
color: white;
}
</style>
You can use content-class="your-class" in the vue bootstrap modal.
<b-modal id="myModal" content-class="your-class" title="BootstrapVue">
Body Content
</b-modal>
Or else it is difficult to style the modal cuz the normal class="" does not apply to the code.
