问题 I am trying to get a magnifying glass as the background for my input element. The magnifying glass icon is part of a CSS sprite that looks like this: To position it, I've used these properties: #search-form input[type="text"] { background: url('../images/icons.png') no-repeat left center; background-position: 0px -30px; border: 1px solid #a9e2ff; padding: 3px; width: 200px; font-size: 1em; padding-left: 20px; } But the background still appears at the top of the input box rather than aligned

How to add custom HTML Tags to Visual Studio and Avoid Squiggly Lines

由 丶灬走出姿态 提交于 2019-12-01 16:26:21
I'm using Visual Studio 2013 to create raw HTML pages (i.e. index.html). In my HTML I am implementing custom HTML tags. As such, Visual Studio underlines my custom tags with squiggly lines (due to the warning of "Unknown element ..."). In hopes to get rid of the squigglies, I added my custom tags to the list of "Tag Specific Options" via Tools > Options > Text Editor > HTML (Web Forms) > Formatting > Tag Specific Options . However, the squiggly lines persist. Is there a way to inform VS2013 that my custom HTML tags are valid (i.e. keep VS2013 from underlining my custom tags with squigglies)?

Set custom MarkupExtension from code

由 懵懂的女人 提交于 2019-12-01 04:37:02
How do you set a custom MarkupExtension from code? You can easily set if from Xaml. The same goes for Binding and DynamicResource . <TextBox FontSize="{Binding MyFontSize}" Style="{DynamicResource MyStyle}" Text="{markup:CustomMarkup}"/> Setting the same values through code behind requires a little different approach Binding: Use textBox.SetBinding or BindingOperations.SetBinding Binding binding = new Binding("MyFontSize"); BindingOperations.SetBinding(textBox, TextBox.FontSizeProperty, binding); DynamicResource: Use SetResourceReference textBox.SetResourceReference(TextBox.StyleProperty,

What's the difference between the lang attribute and the <meta http-equiv=“Content-Language” content=“en-US”> tag?

由 我与影子孤独终老i 提交于 2019-12-01 02:18:23
I was wondering what's the significance of using the "lang" attribute and how that differs from using the meta "Content-Language" tag? Consider the following code: <html lang="en"> <head> <meta http-equiv="Content-Language" content="en-US"> </head>... My assumption is that the browser is reading the meta tag's value, but the DOM is concerned with the "lang" attribute. Is this correct? Are there any nuances I'm unaware of? The lang attribute (on the HTML element) specifies the language for the document (unless overridden with another lang attribute which can change the language for a section of

Making user-made HTML templates safe

由 落花浮王杯 提交于 2019-11-30 23:48:38
I want to allow users to create tiny templates that I then render in Django with a predefined context. I am assuming the Django rendering is safe (I asked a question about this before ), but there is still the risk of cross-site-scripting, and I'd like to prevent this. One of the main requirements of these templates is that the user should have some control over the layout of the page, not just it's semantics. I see a couple of solutions: Allow the user to use HTML, but filter out dangerous tags manually in the final step (things like <script> and <a onclick='..'> . I'm not so enthusiastic

Converting HTML markup to a RTF document

由 强颜欢笑 提交于 2019-11-30 23:43:22
I have an XML document containing embedded HTML content that I am attempting to convert to an RTF output file. I have the XML elements decorated with <li>, <p>, <b> and other HTML markup, that I would like to have transferred into the generated RTF. Here is what works as of now: Fetch XML tag content as string (containing HTML tags for line breaks, paragraph breaks, and lists) Write the XML tag content to an RTF file. I am using Python scripts to achieve the conversion. Also being used is ElementTree (to parse input XML) PyRTF-NG (to convert from HTML to RTF), a library that handles tables and
