为何文本溢出class为header-menu的div？需将文本置于LOGO前方

Hey there! Let's work through getting that text positioned neatly in front of your logo without it spilling outside the .header-menu div. Based on what you've shared, here are practical fixes you can test out:

1. Fix container positioning & overflow first #

First, make sure your .header-menu div is set up to contain its child elements properly. Add these CSS rules to establish a solid base:

.header-menu {
  position: relative; /* Critical for any absolute positioning inside */
  display: flex; /* Aligns logo and text in a row */
  align-items: center; /* Vertically centers both elements */
  overflow: visible; /* Ensures text doesn't get clipped accidentally */
}

2. Position text directly over the logo #

If you want the text to overlay the logo (not just sit next to it), use z-index and absolute positioning. Let's assume your logo has a class .logo and your text is wrapped in a .header-text element:

.header-menu .logo {
  z-index: 1; /* Puts the logo behind the text */
}

.header-menu .header-text {
  position: absolute;
  left: 15px; /* Adjust this value to shift text over the logo */
  z-index: 2; /* Ensures text sits on top */
  color: #ffffff; /* Tweak color to contrast with your logo */
}

Pro tip: The position: relative on .header-menu ensures the absolute-positioned text stays contained within the div.

3. Reorder elements with flexbox (for side-by-side layout) #

If you just want the text to appear before the logo in the layout (left side, in front visually), flexbox makes this easy—even if your HTML has the logo first:

.header-menu {
  display: flex;
  gap: 10px; /* Adds space between text and logo */
}

.header-text {
  order: -1; /* Moves text to the front of the flex container */
}

This keeps both elements inside .header-menu and aligns them exactly how you want.

4. Double-check for invalid HTML #

Sometimes text spills outside a div because of unclosed tags in your markup. Quickly verify that all elements inside .header-menu are properly nested—for example, make sure your text is wrapped in a <span>, <p>, or <div> that's fully contained within .header-menu.

If none of these fix it, sharing a small snippet of your actual HTML and CSS would help narrow things down further!
