响应式CSS：防止搜索栏和按钮在放大时变大？

Question

我在大约一年前创建了一个响应式网站，并采用了大商业主题并将其改为我自己的主题。我在标题的搜索栏旁边放了一个按钮。为了测试响应性，我放大和缩小以查看会发生什么。当我这样做时，搜索栏和按钮似乎移动了很多并变得更大。我希望它像标题，包按钮和电话号码一样保持不变。这是我的代码......

/* CSS */
#SearchForm2 {
    position: absolute;
    right: 0;
    top: 3%;
    z-index: 52;
    width: 25%;
    height: auto;
    display: block;
}
#SearchForm2 form {
    padding: 0;
    margin: 0;
    display: block;
}
#SearchForm2 label {
    display: none;
}
#SearchForm2 input {
    display: block;
    height: auto; 
    width: auto;
    font-weight: 400;
    text-transform: uppercase;
    padding: 2px 3px 2px 3px;
}
#SearchForm2 p {
    display: none;
    margin: 5px 0 0 0;
}
#SearchForm2 input.Textbox {
    float: right;
    font-size: 100%;
    width: 59%;
    height: auto;
    display: block;
    padding: .5em 1em;           
    text-transform: none;
    line-height: 17px;
    background-color: transparent; 
    border: 1px solid #000;
    vertical-align: middle;
}
.searchbtn2 {
    float: right;
    width: 39%;
    height: auto;
    font-size: 100%;
    display: block;
    margin: 0px 3px 0 0;
    cursor: pointer;
    font-weight: 500;
    text-transform:uppercase;
    font-family: "Cabin", Arial, Sans-serif;
     *display: inline;
     *zoom:1;
    text-align: center;
    vertical-align: middle;
    border: none;
    padding: 5px 10px 4px 10px;

    -webkit-transition: all 0.3s;
    -moz-transition: all 0.3s;
    transition: all 0.3s;
    background-color: #454545;
    color: #fff;
    border: 2px solid #454545;
}
.searchbtn2:hover {
    background-color: #ffffff;
    color: #000;
}

<!-- Header Search -->
<div id="SearchForm2">
  <form action="%%GLOBAL_ShopPath%%/search.php" method="get" onsubmit="return check_small_search_form(this)">
  <label for="search_query">%%LNG_Search%%</label>
    
    <input type="text" name="search_query" id="search_query" class="Textbox autobox" value="%%LNG_Search%%" />

    <button type="submit" class="searchbtn2" name="Search" title="Search">Search</button>
  </form>
</div>

Answer 1

您使用的是字体大小的百分比。随着投入的增加，百分比也会增加。如果您不希望发生这种情况，则需要停止使用#SearchForm2 input.Textbox上的百分比和.searchbtn2

此外，这不是我建议测试响应性的方式。如果您使用Chrome，请打开开发人员工具并选择“切换设备工具栏”按钮以获得更准确的表示。

Answer 2

按钮拉伸是由使用响应单位设置按钮的宽度引起的。

提到代码行：width: 39%。

在拉伸页面时，您必须将宽度值更改为静态单位，以使它们保持相同的宽度。
