CSS text-indent on input field doesn't update the caret position until you start typing

阅读更多关于 CSS text-indent on input field doesn't update the caret position until you start typing

问题 When I use text-ident property in CSS, what I expect to see is when you focus into the text input area, the text cursor icon/caret will appear indented. But it appears as if it isn't indented until you type for first character. The only work around is to use left padding on the input element, but I want to avoid using padding because I am also setting a width and don't want to have to implement a padding fix for IE using an IE specific spreadsheet. This bug happens in Safari. See below for

CSS的文本属性

阅读更多关于 CSS的文本属性

CSS 文本属性可定义文本的外观。通过文本属性，可以改变文本的颜色、字符间距，对齐文本，装饰文本，对文本进行缩进等。㈠缩进文本 text-indent 通过使用 text-indent 属性，所有元素的第一行都可以缩进一个给定的长度，甚至该长度可以是负值。 ⑴使用负值比如“悬挂缩进”，即第一行悬挂在元素中余下部分的左边，如下所示： p {text-indent: -6em;} 不过在为 text-indent 设置负值时要当心，如果对一个段落设置了负值，那么首行的某些文本可能会超出浏览器窗口的左边界。为了避免出现这种显示问题，建议针对负缩进再设置一个外边距或一些内边距，如下所示： p {text-indent: -6em; padding-left: 6em;} ⑵使用百分比值百分数要相对于缩进元素父元素的宽度。换句话说，如果将缩进值设置为 20%，所影响元素的第一行会缩进其父元素宽度的 20%。在下例中，缩进值是父元素的 20%，即 100 个像素： div {width: 500px;} p {text-indent: 20%;} <div> <p>this is a paragragh</p> </div>⑶利用text-indent属性演示如何缩进文本首行。㈡水平对齐 text-align text-align 属性规定元素中的文本的水平对齐方式。

Or is there anotherway of pushing text out of the textbox? 回答1: #paaa { text-indent:50px; display: block; line-height: 1; } Add line-height to make it work in IE.

Do search engines treat text-indent:-9999em or negative margin as SEO cheat?

阅读更多关于 Do search engines treat text-indent:-9999em or negative margin as SEO cheat?

问题 I want to use a technique like text-indent:-9999em or negative margin to replace my text with more pretty pictures, but I wonder if search engines would treat this as kinds of cheating? I think for it to know this, it must read my CSS file, so I can use robots.txt to forbid it from reading my CSS file. If this works, can I also use display:none directly? Or I can manipulate some web-element's style by using jQuery code? 回答1: The techniques you have outlined (negative margins/indents) etc are

问题 I'm using CKEditor and I want to indent just the first line of the paragraph. What I've done before is click "Source" and edit the <p> style to include text-indent:12.7mm; , but when I click "Source" again to go back to the normal editor, my changes are gone and I have no idea why. My preference would be to create a custom toolbar button, but I'm not sure how to do so or where to edit so that clicking a custom button would edit the <p> with the style attribute I want it to have. 回答1:
