placeholder

问题 Can I do something like this with pure html and if needed css and javascript: And when the mouse focuses, it becomes like this: So I was thinking of an image placeholder. Am I on the right track, or is there a better/more simpler or more straightforward method?

问题 I create my from, define my TextBoxes, and for my placeholder text I'm using the following code: $AssetText.Add_MouseClick({ $AssetText.text = “” }) $ErrorText.Add_MouseClick({ $ErrorText.text = “” }) $IssueText.Add_MouseClick({ $IssueText = “” }) $TestTagText.Add_MouseClick({ $TestTagText.text = “” }) $TroubleshootText.Add_MouseClick({ $TroubleshootText.text = “” }) $ResolutionText.Add_MouseClick({ $ResolutionText.text = “” }) It works to remove text from the TextBox, but if I type a fair

问题 I am having trouble with a placeholder. I would like to change the color of the asterisk inside of the placeholder to red and leave the rest the dim black.

问题 I have need for an open format to write stories in a generic way (with placeholder/variables). To make the stories case specific I would like to set a list of key/value pairs and apply them when publishing. I also want to separate styling from content so I can easily publish to web, pdf etc. Example: @varname@ is a great place. I chose Markdown to solve the content/styling separation but I do not know an easy way to parameterize certain parts of the text and have them filled in when I

问题 I've done a bunch of googling, but I can't find an answer anywhere that works for me. I'm creating a form (for the first time ever) and I need a red asterisk directly next to the placeholder text in the input boxes. Embarrassingly, this is the closest I have been able to get so far: form { margin: 0 auto; background-color: #3d549a; } input { font-family: avenir; font-size: 17px; color: #ffffff; font-weight: 100; border: none; width: 400px; padding: 15px; border-radius: 5px; } textarea {

问题 When developing a web page/application, I often don't have all the data right upfront. Sometimes I need to put dummy text and images in places to get the overall feel of how its going to look. For dummy text, I can use Lorem Ipsum to generate such junk text. But how can I do something similar with images? 回答1: Similar to Lorem Ipsum, theres this one: Lorem Pixel This generates placeholder images for your html if the specified size. The url of the site follows the pattern : http://lorempixel

问题 I am a fan of using HTML placeholders, as it helps describe to the user what sort of content they need to input. However, sometimes you need to give the user more information than just a simple sentence. Basically I'd like to be able to add line breaks, tabs, etc. into my textarea placeholder. I've heard of using special coding to do this (And have written pieces of code using these), but I find it rather unreliable. For example, certain browsers will display different amounts of white space

问题 my aim is to write a little prove assistant in prolog. My first step is to define the logical connectives as follows: :-op(800, fx, -). :-op(801, xfy, &). :-op(802, xfy, v). :-op(803, xfy, ->). :-op(804, xfy, <->). :-op(800, xfy, #).

I tried to solve my problem in the following way: X # Y :- X v Y; X & Y; X -> Y; X <-> Y. but the
