The cleanest way to fix this is to apply the vertical-align: top property to you CSS rules: #div1 div { width:30px;height:30px; border:blue 1px solid; display:inline-block; *display:inline;zoom:1; margin:0px;outline:none; vertical-align: top; } If you were to add content to your div‘s, then using either line-height: 0 or font-size: 0 would cause problems with your text layout.

It will remove an initial line feed character at the start of <textarea> and <pre> elements and also on the invalid <listing> element, … Read more
If you are more interested in the bits that are not whitespace, you can match the non-whitespace instead of splitting on whitespace. ” The quick brown fox jumps over the lazy dog. “.match(/\S+/g); Note that the following returns null: ” “.match(/\S+/g) So the best pattern to learn is: str.match(/\S+/g) || []
I would build a custom extension method using StringBuilder, like: public static string ExceptChars(this string str, IEnumerable<char> toExclude) { StringBuilder sb = new StringBuilder(str.Length); for (int i = 0; i < str.Length; i++) { char c = str[i]; if (!toExclude.Contains(c)) sb.Append(c); } return sb.ToString(); } Usage: var str = s.ExceptChars(new[] { ‘ ‘, ‘\t’, ‘\n’, … Read more
The <<- form of heredoc only ignores leading whitespace for the end delimiter. With Ruby 2.3 and later you can use a squiggly heredoc (<<~) to suppress the leading whitespace of content lines: def test <<~END First content line. Two spaces here. No space here.
