display value is crucial because it controls how an element behaves in the layout. The most commonly used display values— inline , block , inline-block , and flex —each have distinct behaviors that affect spacing, alignment, and structure.
<p> Let's break them down one by one so you can understand when to use each.
Inline Elements: Flow Like Text
<p>display: inline makes an element behave like a word in a sentence. It doesn't start on a new line and only takes up as much width as its content.
- You can't set width or height directly.
- Vertical margins (top/bottom) won't push other elements away.
- Padding and borders do apply but might not behave exactly as with block elements.
<span></span> , <a></a> , or <strong></strong> to sit within a line of text without breaking the flow.
<p> Example:<span>This is inline</span> <span>This is also inline</span><p> These two will appear side by side unless there's not enough space.
Block Elements: Take Full Width
<p>display: block turns an element into a block box. These elements stack vertically and take up the full available width by default.- They always start on a new line.
- Width and height can be controlled.
- Margins and padding work as expected in all directions.
<div> , <p> , <header> , or anything that should stand alone on a line.<p> Example:<div style="display: block">Block 1</div> <div style="display: block">Block 2</div><p> Each div appears on its own line, stacked vertically.
Inline-Block: Block Features Without Line Breaks
<p>display: inline-block combines features from both worlds. It allows you to set dimensions and spacing like a block, but it flows inline with surrounding content.- Doesn't start on a new line.
- Respects width, height, margins, and padding.
- Sensitive to vertical alignment (useful for aligning elements side by side with control).
<span style="display: inline-block; width: 100px">Box 1</span> <span style="display: inline-block; width: 100px">Box 2</span><p> Both boxes sit next to each other and respect the width setting.<p> One thing to note: Inline-block elements may have small gaps between them due to whitespace in HTML. To fix this, you can:
- Remove spaces between HTML tags
- Use negative margins
- Set
font-size: 0on the parent
Flexbox: Layout Made Easier
<p>display: flex is a modern layout mode designed to help you build complex layouts more easily.- Applies to the container, affecting its children (called flex items).
- Items are laid out in a row or column automatically.
- Alignment, spacing, and order can be controlled with simple properties like
justify-content,align-items, andgap.
<div style="display: flex; justify-content: space-between"> <div>Item 1</div> <div>Item 2</div> <div>Item 3</div> </div><p> This creates a horizo??ntal layout with even spacing between items. <p> Key benefits:
- No need to float or clear elements
- Built-in alignment tools
- Responsive behavior with minimal code
Final Thoughts
<p> Each display type has its place depending on what you're trying to achieve.inline and block are foundational and still widely used. inline-block gives more control for inline layouts. And flex is the go-to choice for modern layout needs.
<p> You'll often switch between them depending on context—like using flex for containers and block or inline-block inside those containers.
<p> Basically, just remember:
-
inline: goes with the flow -
block: starts fresh -
inline-block: same line, but sized -
flex: let the container handle the layout

如何僅在某些頁(yè)面上包括CSS？
Jun 11, 2025 am 12:01 AM
選擇性包含CSS在特定頁(yè)面上的方法有三種：1.內(nèi)聯(lián)CSS，適用於不常訪問(wèn)或需要獨(dú)特樣式的頁(yè)面；2.使用JavaScript條件加載外部CSS文件，適合需要靈活性的情況；3.服務(wù)器端包含，適用於使用服務(wù)器端語(yǔ)言的場(chǎng)景。這種方法可以優(yōu)化網(wǎng)站性能和可維護(hù)性，但需平衡模塊化與性能。
