Lazy image loading with semantic markup

由 二次信任 提交于 2021-02-05 06:43:45
问题 I have a very image-rich site. To conserve bandwidth for users, I would like to lazy-load images as they enter the view-port. There are assorted jQuery plugins and similar that accomplish this. This comes at the price of placing the actual image url, not in the src attribute but someplace else. This makes the markup less nice, and worse, less intelligible for search engine crawlers. Is there way to have both lazy image loading and semantic, search-engine-friendly markup? 回答1: You do not need

Style attribute vs setting ID and external Css

由 与世无争的帅哥 提交于 2021-01-27 05:18:03
问题 I understand the concept of keeping all presentational elements outside of the markup and putting them into an external .css file. I want to get a feel for what types of situations you'd justify use of the style attribute vs setting IDs and external Css. To this point, I've used the style attribute a lot, I usually use it to specify presentation items specific to that element and anything that is for all elements I pull into an external css file but I'd like to reevaluate my position and make

问题 I can't figure out the difference between valign vs text-align in HTML in context with the following code: <table width="500" border="0"> <tr> <td colspan="2" style="background-color:#FFA500;"> <h1>Main Title of Web Page</h1> </td> </tr> <tr valign="top"> <td style="background-color:#FFD700;width:100px;text-align:top;"> <b>Menu</b><br /> HTML<br /> CSS<br /> JavaScript </td> <td style="background-color:#EEEEEE;height:200px;width:400px;text-align:top;"> Content goes here</td> </tr> <tr> <td

Append markup string to a tag in BeautifulSoup

由 孤者浪人 提交于 2020-05-15 03:51:29
问题 Is it possible to set markup as tag content (akin to setting innerHtml in JavaScript)? For the sake of example, let's say I want to add 10 <a> elements to a <div> , but have them separated with a comma: soup = BeautifulSoup(<<some document here>>) a_tags = ["<a>1</a>", "<a>2</a>", ...] # list of strings div = soup.new_tag("div") a_str = ",".join(a_tags) Using div.append(a_str) escapes < and > into < and > , so I end up with <div> <a1> 1 </a> ... </div> BeautifulSoup(a_str) wraps this in <html

问题 Okey, so, recently, i found this: https://angularjs.org/ I noticed that they use custom attribute prefix "ng-" From articles, like: http://html5doctor.com/html5-custom-data-attributes/ or even stackoverflow: https://stackoverflow.com/a/17091848/2803917 And there are many more, the only VALID (im not talking about the fact, that they work anyways) prefix to use is "data-". So, could someone explain to me, how can it be, that these, million projects and companies, uses an invalid prefix for

Dealing with ASP.NET MVC “tag soup”

由 不羁岁月 提交于 2020-02-28 05:53:44
问题 I was working on an ASP.NET MVC template today, and after staring at all those fluorescent yellow % tags for long enough, I basically decided I had had enough, so I painstakingly modified my ascx file to look like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% if (Model == null) { %> <%= ViewData.ModelMetadata.NullDisplayText %> <% } else if (ViewData.TemplateInfo.TemplateDepth > 1) { %> <%= ViewData.ModelMetadata.SimpleDisplayText %> <% } else { %> <% foreach

Prevent section heading to subtitle transformation in reStructuredText

由 被刻印的时光 ゝ 提交于 2020-01-25 07:13:07
问题 In reStructuredText, a heading followed by a lower-level heading is read as a subtitle: Section 1 ========= Subtitle -------- However, what if I actually want a subsection heading to follow immediately after a section heading? According to the the docs, an empty comment "serves to terminate a preceding construct" , but this doesn't seem to apply here, as Section 1 ========= .. Section 2 --------- still gets turned into a heading for Section 1 , followed by a subtitle Section 2 by, for example
