Question

我对占位符有问题，不管我做什么，它总是大写的。我试图添加我能找到的所有应该有帮助的css样式，但到目前为止还没有运气。有人能告诉我为什么会这样吗？

我的搜索栏的css

#navigation-bar {
    height: 100%;
    width: 500px;
    float: right;
}

#search {
    position: absolute;
    top: 0;
    right: 0;
    width: 60px;
    height: 100%;
}

#label {
    width: 60px;
    height: 100%;
    position: relative;
    z-index: 20;
}

#label label {
    display: block;
    width: 60px;
    height: 100%;
    background: url("../../images/search.png") no-repeat center center;
    font-size: 0;
    color: rgba(0, 0, 0, 0);
    text-indent: -9999px;
    cursor: pointer;
}

#label label:hover {
    background: url("../../images/search.png") no-repeat center center;
}

#label.active label {
    background: url("../../images/search.png") no-repeat center center;
}

#input {
    position: absolute;
    top: 0;
    right: 60px;
    width: 450px;
    height: 100%;
    z-index: 5;
    overflow: hidden;
}

#input input {
    display: block;
    position: absolute;
    top: 0;
    right: -450px;
    width: 450px;
    height: 100%;
    margin: 0;
    padding: 0 10px;
    border: none;
    background-color: #333;
    color: #fff;
    font-size: 18px;
    backface-visibility: none;
    border-radius: 0;
    transition: left 0;
}


#input input:focus {
    outline: none;
}

#input.focus {
    z-index: 20;
}

#input.focus input {
    right: 0;
    transition: right 0.3s;
}


::-webkit-input-placeholder {
    text-transform: none;
}
:-moz-placeholder {
    text-transform: none;
}
::-moz-placeholder {
    text-transform: none;
}
:-ms-input-placeholder {  
    text-transform: none;
}

HTML

<div class="content-container">
    <div class="top-wrapper">
        <div class="top">
            <div class="navigation">
                <div class="container">
                    <div class="navbar-collapse collapse">
                        <div id="navigation-bar" class="clearfix">
                            <form id="search" onkeypress="return event.keyCode != 13;" action="@Model.SearchPageUrl" method="post">
                                <div id="input"><input type="text" name="search-terms" id="search-terms" placeholder="@Model.SearchPlaceholder"></div>
                                <div id="label"><label for="search-terms" id="search-label">search</label></div>
                            </form>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

Answer 1

I dont think you can just do ::-webkit-input-placeholder

try with specificying the input first like so:

input::-webkit-input-placeholder {
   text-transform: lowercase;
}

Answer 2

我不仅会做@Brad所说的话，而且还会为你的风格添加!important。这有望确保没有其他样式接管您的输入元素。不幸的是，你无法检查＆＃34;占位符属性（至少我还没能）

input::-webkit-input-placeholder {
    text-transform: none !important;
}
input:-moz-placeholder {
    text-transform: none !important;
}
input::-moz-placeholder {
    text-transform: none !important;
}
input:-ms-input-placeholder {  
    text-transform: none !important;
}

我也建议改为使用inherit：

input::-webkit-input-placeholder {
    text-transform: inherit !important;
}
input:-moz-placeholder {
    text-transform: inherit !important;
}
input::-moz-placeholder {
    text-transform: inherit !important;
}
input:-ms-input-placeholder {  
    text-transform: inherit !important;
}

Answer 3

::-webkit-input-placeholder {
    text-transform: none;
}
:-moz-placeholder {
    text-transform: none;
}
::-moz-placeholder {
    text-transform: none;
}
:-ms-input-placeholder {  
    text-transform: none;
}

你写的这段代码，做你想要的，它应该工作。我认为你应该检查它是否被其他更精确的CSS选择器覆盖。尝试添加更精确的选择器来检查它，例如：

body input#search-terms::-webkit-input-placeholder {
    text-transform: none;
}
body input#search-terms:-moz-placeholder {
    text-transform: none;
}
body input#search-terms::-moz-placeholder {
    text-transform: none;
}
body input#search-terms:-ms-input-placeholder {  
    text-transform: none;
}
