Is there a way in CSS to make an element's width be 100% minus the width of other elements?
A solution is to utilize flexbox by adding the class "some-container" to the parent element and the class "expand" to the element that should take up the remaining space. This allows for dynamic and flexible layout adjustments. Check out the example below and experiment with resizing the window. For more comprehensive insights on flexbox, refer to the detailed tutorial provided by CSS Tricks.
Key points from the CSS breakdown:
display: flex
on .some-container
specifies that this element will use flexbox properties.
flex: 1
on .expand
indicates that this element should expand within its parent container based on available space.
.some-container { display: flex; }
.expand { flex: 1; }
<div class="some-container">
<h1>some header</h1>
<input class="expand" type="text">
<button>some button</button>
</div>
