After my analysis, it appears that the spacing on both sides should align the two components perfectly in the div
It seems like there's a slight error in your calculations. Your equation 200+9+10+50+9 gives you a total of 278, which matches the width of the element at 278. However, you forgot to account for the space introduced between the two input elements due to the new line (Why does the browser render a newline as space?).
If you eliminate that newline, everything should function as expected:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
input {
outline: none;
}
.search-box {
height: 50px;
width: 280px;
border: 1px solid #DCDCDC;
background-color: #F5F5F5;
margin: 10px auto;
border-radius: 10px;
box-shadow: 2px 2px 1px #D3D3D3, -2px 2px 1px #D3D3D3;
}
#input-search {
width: 200px;
height: 30px;
border: 1px solid #DCDCDC;
margin: 9px 10px 9px 9px;
border-radius: 5px;
text-indent: 3px;
}
#btn {
height: 30px;
width: 50px;
font-size: 12px;
font-weight: 600;
color: #fff;
border-radius: 5px;
border: 1px solid #008080;
display: inline-block;
margin: 9px 9px 9px 0;
background-image: linear-gradient(#20B2AA, #5F9EA0);
}
<div class="search-box">
<input type="text" id="input-search" placeholder="search"><!--
--><input type="button" value="GO" id="btn">
</div>
To prevent such issues, consider utilizing display: flex instead of manually determining element widths.
- Change the
display property of your .search-box to flex.
- Remove the explicit
width and height from both input elements to let flex handle it.
- Rather than setting a fixed
width for #btn, apply desired padding values.
- Utilize
flex: 1 1 auto; on #input-search to allow it to stretch and occupy available space.
This approach enables adjusting the width of your .search-box without modifying input element widths, making button and text updates easier. The responsiveness can be enhanced by replacing width with max-width for .search-box.
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
input {
outline: none;
}
.search-box {
height: 50px;
width: 280px;
border: 1px solid #DCDCDC;
background-color: #F5F5F5;
margin: 10px auto;
border-radius: 10px;
box-shadow: 2px 2px 1px #D3D3D3, -2px 2px 1px #D3D3D3;
display: flex;
}
#input-search {
border: 1px solid #DCDCDC;
margin: 9px 10px 9px 9px;
border-radius: 5px;
text-indent: 3px;
flex: 1 1 auto;
}
#btn {
font-size: 12px;
font-weight: 600;
color: #fff;
border-radius: 5px;
border: 1px solid #008080;
display: inline-block;
margin: 9px 9px 9px 0;
padding-left: 15px;
padding-right: 15px;
background-image: linear-gradient(#20B2AA, #5F9EA0);
}
<div class="search-box">
<input type="text" id="input-search" placeholder="search">
<input type="button" value="GO" id="btn">
</div>
To enhance the CSS further, consider removing margin from the input elements and switching to padding within .search-box along with using gap. For #btn, opt for using em units for padding rather than px.
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
input {
outline: none;
}
.search-box {
height: 50px;
width: 280px;
border: 1px solid #DCDCDC;
background-color: #F5F5F5;
margin: 10px auto;
border-radius: 10px;
box-shadow: 2px 2px 1px #D3D3D3, -2px 2px 1px #D3D3D3;
display: flex;
padding: 9px;
gap: 10px;
}
#input-search {
border: 1px solid #DCDCDC;
border-radius: 5px;
text-indent: 3px;
flex: 1 1 auto;
}
#btn {
font-size: 12px;
font-weight: 600;
color: #fff;
border-radius: 5px;
border: 1px solid #008080;
display: inline-block;
padding-left: 1.2em;
padding-right: 1.2em;
background-image: linear-gradient(#20B2AA, #5F9EA0);
}
<div class="search-box">
<input type="text" id="input-search" placeholder="search">
<input type="button" value="GO" id="btn">
</div>
