The problem
Recently, I had to extend a div element to the maximum width to right for a design effect. In my case, the element had to overflow its parent and extend itself at the end of the horizontal viewport.
As an idea, the following code can be a good HTML example:
<div class="parent">
<div class="child">
</div>
<div class="child">random text</div>
</div>So, with width: 100vw on the parent and background-color on the child, the element overflowed outside of my body and html elements.
The solution
I had to set overflow-x: hidden; to html and body.
html, body{
overflow-x: hidden;
}
