How can I change the length of a text_field in rails?
提问by klondike-5-3226
So I have this text field
所以我有这个文本字段
<%= f.text_field :body, placeholder: "Make an offer ", :maxlength=>"254" %>
right now it takes up 100% of the width of the box it is in. I want it to take up like 95%. So far I have tried (from other forum posts)
现在它占据了它所在盒子宽度的 100%。我希望它占据 95%。到目前为止我已经尝试过（来自其他论坛帖子）
adding :columns => "50"this didn't affect it. I tried
putting on an html tag , :html => { :id => "offer_form" }and then putting in my css file
添加:columns => "50"这并没有影响它。我尝试放置一个 html 标签，:html => { :id => "offer_form" }然后放入我的 css 文件
#offer_form { width:50%;}
this didn't work
这没有用
any other suggestions?
还有其他建议吗？

I realized that in my css file I have under /forms/
我意识到在我的 css 文件中我有 / forms/
input, textarea, select, .uneditable-input {
border: 1px solid #bbb;
width: 98%;
padding: 10px;
height: auto !important;
margin-bottom: 15px;
}
and when i change the width here it works. but it affects all of the forms in the entire app (obviously)(ie they are all 98%). Is there a way that I can id just this field so that I can edit its width independently.
当我在这里更改宽度时，它会起作用。但它会影响整个应用程序中的所有表单（显然）（即它们都是 98%）。有没有办法可以只识别这个字段，以便我可以独立编辑它的宽度。

Use CSS. The width of the field isn't related to its maximum characters.
使用 CSS。字段的宽度与其最大字符数无关。
input.body {
width:95%;
}

add :size=>"50"option to text_field
:size=>"50"向 text_field添加选项
<%= f.text_field :body, :size=>"50", placeholder: "Make an offer ", :maxlength=>"254" %>
