Question
Answer and Explanation
To create two dropdowns with no gap between them using HTML and CSS, you will primarily need to use CSS to adjust the default spacing around the select elements.
Here’s a breakdown of how to achieve this:
1. HTML Structure: Begin by setting up your HTML with two <select> elements wrapped in a container.
<div class="dropdown-container">
<select>
<option value="option1">Option 1</option>
<option value="option2">Option 2</option>
</select>
<select>
<option value="optionA">Option A</option>
<option value="optionB">Option B</option>
</select>
</div>
2. CSS for No Gap: The crucial part is applying CSS that eliminates the margin and padding between and around the <select> elements.
Here’s an example of the needed CSS:
.dropdown-container {
display: inline-flex; / or use display: flex /
}
.dropdown-container select {
margin: 0;
border-radius: 0; / removes default select box rounding. Optional /
padding: 8px; / or set to any padding if needed/
border-right: none; / If no gap between the boxes, no need to show this right border/
}
.dropdown-container select:last-child {
border-left:none;
border-radius:0; /remove roundings for better visual continuity/
}
3. Inline-flex (Or flex):
Using inline-flex, or the `flex` layout for the container helps the select elements to line up nicely and not wrap to the next row.
By default the `select` elements add some margins that you might not like when combining two `select` elements. With `flexbox` and proper padding you are able to achive this no gap behavior with the use of above CSS. You might want to adjust the styles like the `border-radius` and the border that they create on right or left of those two `select` elements to create a single object as a visual appearance.
Important: When modifying padding and margin properties you might experience differences depending on the User-agent stylesheet.
To fix the different browsers differences you might need to modify also box-sizing with adding
{
box-sizing:border-box;
} for applying your box-sizing method accross the page, then you must
use all padding or margin properties, to fine tune your dropdown to create what your client, team or the requirements want.
With the use of these css changes, your select boxes now sit perfectly flush with no gap between them.
